What is Reddit's opinion of Dependency Walker?

From 3.5 billion Reddit comments

It's almost always a bad idea to go on a DLL quest, but if you were doing so responsibly*, this is the tool that helps the most.

* When the software vendor no longer exists, and when no support can be found, and when google searches become ambiguous, and you are running in a secure virtual environment, only then are you blessed to continue.

For anyone else migrating their way out of DLL hell these are lifesavers:

Sysinternal ListDLLS https://docs.microsoft.com/en-us/sysinternals/downloads/listdlls (2008 and later)

Dependency Walker http://www.dependencywalker.com/ (Everything as far back as Windows 98)

Two ways that I can think of:

1. Forget it and use ShareX.

2. Install Autohotkey and bind #+S to launch snipping tool, which is just an executable in System32. Though naturally it has dependency DLLs, and it only checks for them in the current folder, instead of PATH. So use Dependency Walker to see which ones it needs and copy them away with it.

For Windows I'm compiling with "stack install" and then using Inno Setup to pull the relevant binaries out of the stack install and then package them up into a standard Windows install.exe. My application runs under GTK3, so I'm also having to package up the relevant msys64 library files and install them in the application bin folder. It takes a bit of playing around with pathnames in the Inno Setup file, but once it works the whole thing is automatic.

I also used the Dependency Walker to find out which .dll files I had to bring along.

Try this:

The key part is: >0xC000007B code is defined as 'STATUS_INVALID_IMAGE_FORMAT'.

>Which basically means Rift is trying to load a DLL that Windows thinks is corrupted.

>This can be caused by either:

>a) a 64bit DLL being loaded by a 32bit program (note that Rift is a 32bit program)

>b) A corrupted DLL

>c) Corruption on your hard disk

As per the instructions in that post, I suggest using Dependency Walker (you want the x86 version because Rift is a 32bit program). http://www.dependencywalker.com/

I don't really understand how this is different to the question you asked in your earlier thread but I didn't get a chance to answer so here's my suggestion.

You just run windeployqt and it copies all the files you need to a directory. You can zip up that directory and it should work on other PCs when extracted somewhere. You do not need to make an installer, but users often prefer one.

You'll need to package your C++ runtime along with it. I'm not sure how windeployqt handles that if you compiled with MinGW rather than Visual Studio. I noticed that for Visual C++ it includes the "vcredist" which is an installer the user needs to run to install the runtime. However I know that you can actually just include the relevant runtime DLLs (usually msvcpXXX.dll and possibly msvcrXXX.dll where XXX is the Visual Studio version number).

The target PC should be up-to-date. I've seen applications fail to run but a Windows Update fixed it.

If your application fails to run, you can run Dependency Walker on it. It always gives a few false positives but you get used to which ones they are and it can highlight any missing DLLs.

Hope that helps.

As a simple sanity check, I would re-point to the DLLs on the new PC, and re-select there methods from the library node configuration window. LabVIEW is very finicky when it comes to loading libraries, so I always try this.

If that doesn't fix it, my best guess would be a dependency issue.

You can download this application and check the DLL dependencies on each PC. It can be hard to read at times, but if you post a screen cap of the results on each PC I can try and help you further.

Exes depend on libraries. At minimum, a C executable on Windows will depend on the C runtime library. To see the dependencies, check out the free dependency walker tool.

Edit: Actually, thanks for posting this. It made me run depends.exe on my FOSS project CSVfix, which I was about to release, and made me realise that compiling with the mingw-builds compiler as opposed to TDM introduced run-time dependencies that I don't want.

download dependency walker http://www.dependencywalker.com/

open it and > CTRL + O and open the .exe from whatever game
(the program will run the game and try to find any errors)

now the results are going to be divided into 2 sections, the first on top doesn't matter, ignore it. the second part on bottom will be a sort of logs of what the program did as he opened the program here is where you will find the error.

now you ignore logs with with the yellow question mark. scroll down and find any problems that appear with red letters, on the left side it's the module with the name.

in my case its almost always a d3dx9 file. this is a directX dll, download the directX installer from windows official site and download it.

go to c/Windows locate folder System32 and file your faulty .dll and delete it, do the same with the SysWOW64 folder, same .dll will be there, delete it.

run the installer and it will re-install that .dll and it should be working.

also download everything other people said. usually with dependency walker you will find your problem, but it HAS TO BE .exe file not a launcher, the .exe that takes you directly to the game.

> but it doesn't help

You are not doing it correctly then. Try rebuilding all, and test your executable with the dependency walker. There should be no mfc140.dll in there, if there is you are doing something wrong.

DependencyWalker will help you. Open mspaint.exe inside it, and it will scan for all required dependencies for it to run. It can give you a minimum files required list too.

Shader crashes are not necessarily a problem of missing dependencies. It's more likely a problem of your graphics card driver. If DLLs are missing, you would get an error about a missing DLL.

To get a list of all DLLs that are not dynamically loaded you could use the Dependency Walker.

Error 103 might indicate a missing DLL file. Let's check to see if that's the case:

1. Download Dependency Walker (it's free) and extract the files to the D:\Program Files (x86)\OSVR\OSVR-SteamVR\osvr\bin\win64 directory.
2. Open a command prompt by holding down the Windows key on your keyboard and pressing the letter R. In the Run dialog box, type cmd and press Enter.
3. At the command prompt, type: cd "D:\Program Files (x86)\OSVR\OSVR-SteamVR\osvr\bin\win64" and press Enter. The command prompt should change to D:\Program Files (x86)\OSVR\OSVR-SteamVR\osvr\bin\win64>.
4. Type the following command and press Enter: depends.exe /c /f:1 /u:1 /od:driver_osvr.dwi driver_osvr.dll
5. Open a Windows Explorer window and navigate to D:\Program Files (x86)\OSVR\OSVR-SteamVR\osvr\bin\win64. Paste the contents of driver_osvr.dwi into a new gist at https://gist.github.com/ and provide a link.

Thanks!

It's super easy, you need to download a program called Dependency Walker and open it, in the program click the little folder open icon and browse for your fallout3.exe (the game not the launcher) and open it. Once the program opens the file, at the left there's like + and - drop down boxes, go all the way to the top and click the fallout3.exe drop down thing, open the section and close it and it should show you the DLLs that the program uses. Find the ones that are red, download the DLLs and put them in both system32 and the game install directory and the game should work!

Locate the install directory and start the shooter game executable by hand. If the error message is something like 0xc00000007, chances are that you are missing a dll. If that's the case, first, install visual c++ redistributable and directx which come along with Ark. You can find them in your install folder, e.g. C:\Program Files (x86)\Steam\steamapps\common\ARK_CommonRedist

If that doesn't cut it, try copying the stuff from the directx folder into the binary directory, where the shooter game exe lies. Only x86 files if you have a 32 bit OS, otherwise only the x64 ones.

If it still doesn't work, get dependency walker from http://www.dependencywalker.com, install and open the Ark executable from it. It will then tell you what dlls the game is trying to load and which are missing, if any. You can just download them from the Web and copy them next to the exe, ask Google for them and you'll find what you need. This fixed metro redux for me lately, after trying for several hours.

Have you tried IE, Firefox and Opera? Running any anti-virus programs? dll-files from the online might be bad.

http://www.dependencywalker.com/ might be useful?

Good luck, I feel your pain!

That is really unusual. Huh. It should at least give an error message.

If you're somewhat technical you could use task manager to check and see if the dreamseeker.exe process exists after you run it, maybe it's hanging up really early, before it even displays the window.

You could also try http://www.dependencywalker.com/ to see if it's trying to use any libraries that aren't installed on your system but that should just give you an error when you run it and I doubt the rest of BYOND would work.

Other than that I got nothin', sorry. This makes no sense.

I was also getting this error when trying to launch 3DM's Launcher.exe. Googling error code revealed that it stands for missing DLLs or EXEs, so i ran Launcher.exe through the app called DependecyWalker which shows what libs are missing/incorrect and it turned out to be MSVCR100.dll which is a part of VCRedist 2010 (the one i got installed was x86 and you need x64 to run it) after installing VC2010 it worked as expected, and that is crash on loading :D (Windows 8.1)

You are in deep. You need to start small and learn your way along to get a piece of code working.

First, create a simple C DLL with one function...

Create a simple windows DLL by using this information... http://www.codeproject.com/Articles/655071/Basic-Cplusplus-Win-DLL

Next, use "javah" to build the JNI wrapper to code that's going to call the DLL function.

Once you can call a single function in a test DLL, you can move on to the actual DLL from your laser-meter vendor, that has many functions.

Use Dependency Walker to list all of the available functions in the vendor-supplied DLL. Write JNI calls to those functions as you did with your simple single-function test DLL.

http://www.dependencywalker.com/

The code is incorrect, but that would not stop the executable from working. I suggest using Dependency Walker on both machines to check that any DLLs your program may be dependent on are actually there.

Edit: actually, that is the windows message that equates to "illegal memory access" isn't it? In which case the many bugs in your program (as listed by arbostek) are the problem. As to why it works on your PC and not on his - chance, different configurations, different input files (the latter being the most likely).

Hmm... The machine I compiled and ran it on was is a 64 bit Win 7 too. I don't think copying python27.dll from system32 to sysWOW64 is the right solution. What does http://www.dependencywalker.com/ say?

I'll post some later, but I just used depends.exe to manually install an old Excel add-in on a terminal server.

(speaking of old software and terminal servers, ThinApp makes 2003->2008/R2 migrations worry free)

>Maybe I just put 64-bit dlls on a 32-bit folder and that's why it is giving this error?

This is a likely explanation, especially because the naming of these folders is hella confusing -- on 64-bit system the "System32" folder is actually for 64-bit dlls, while the SysWOW64 folder is for 32-bit dlls. So it's very easy to put them in the place they shouldn't go.

But as for sorting out the mess, this is probably going to be difficult. There's a free program called Dependency Walker (http://www.dependencywalker.com/) which might help you to track down which dll is causing you trouble (point it to game's executable and see what it'll tell you) Other than that, am afraid the safest/easiest approach might indeed be to do system reinstall.

Depending on exactly what you want to see, maybe try DLL Export Viewer or Dependency Walker. But really, there's no substitute for actual support; for instance, AFAICT neither of these would suggest to you that including the Microsoft Scripting Runtime DLL as a reference allows you to use Dictionary objects in VBA. I urge you to pester the owner of the DLL(s) in question for support.

Maybe someone has a better answer for you.

You can find undocumented apis with tools like this http://www.dependencywalker.com/

Figuring out the rules on how to call some apis without docs will challange you though. You often will get non helpful errors if you call them incorrectly

Keep in mind that source code for windows have been given under insider program and you can find a lot of it in back corners of internet which helps a lot with understanding how to call something you found that is interesting

Yes, try with dependency walker.

This will only give you the dynamic dependencies on your computer. Say you run your game in OpenGL, it won't show DirectX as a dependency, but it might still use it if available.

If it is a native binary:

• Just analyzing on Windows, use Microsoft sysinternals procmon, to see which files are accessed and how it searches for it.
• On *nix you can use strace
• To see what it does, decompile with ghidra and look at the generated C code.
• To see which windows native functions it uses, you can run the app through dependency walker

Py2exe usually outputs a log with some kind of error in it. Running it from the command line should output something as well.

​

You might have a missing DLL. You can use Dependency Walker to help you figure that out: http://www.dependencywalker.com/

Could you download Dependency Walker (http://www.dependencywalker.com/) and drop the game .exe into it? You might need to copy it out of the game directory for that to work. That will tell us if the game is compiled for Windows or Xbox.

Yes, I'm currently testing through Powershell to get the full error, which is The setup routines for the Lotus Notes SQL Driver (*.nsf) ODBC driver could not be loaded due to system error code 126: The specified module could not be found. (C:\NotesSQL\nsqlc32.dll)

I loaded up Dependency Walker, which steps through a DLL file and checks each dependency in the DLL. It's pulled a handful of dll files (SHCORE.dll, SHLWAPI.dll, etc) and has flagged them as needing to be the 32-bit versions of those files. Because I run Windows x64, I don't want to replace files in my System32 folder, I'd rather just put them elsewhere and have the ODBC driver pull them from the other location.

However, I may have found a solution. I placed a copy of one of the problem files in the ODBC driver's location, and it's now throwing an error against the copy instead of the one in system32. So the next step is to get the 32 bit versions of those dll files and put them into that folder.

I may just set up a 32 bit machine to pull the data, but I was hoping to save some work.

Bummer. Was hoping it'd be that easy lol.

Okay, the program that you can use to help narrow down the issue is called Dependency Walker (http://www.dependencywalker.com/). Download the x86 version (since FFXI is a 32 bit program) and Unzip it, run it with admin privilage -> file -> open -> select pol.exe. Then profile -> start profiling -> OK

When it's done (give it a min) look for stuff that has red, not yellow, in the upper left hand box.. The red things are the major issues that are keeping it from loading. Then you can google some of the dlls it returns to see what it's a part of. I'd almost bet money it has something to do with DirectX 8 but this will help narrow it down for sure.

There may be a number of reasons for the failure; one of them is the different Lua versions of the interpreter you are using and the one that the library is compiled for.

One way to see what happens with the DLL is to use the dependency walker (http://www.dependencywalker.com/). It support "profiling" mode that tracks for DLLs are loaded and reports any errors that happen during those operations. It also shows the dependencies between the dynamic libraries, so you can see if the correct version of the Lua interpreter is being used.

Yeah, I'd be annoyed too. Sorry that this is happening! If you're willing to keep working at it, I can try and help with a bunch of fixes that I've seen other people try.

If you go to this website and download this program http://www.dependencywalker.com/

You can launch Dependencywalker, and click Open.

Select TSLGame.exe and it should see which DLL files it's trying to reference when it runs.

Let me know if any are missing, and I'll see if I can get them somewhere for you.

This error message is unfortunatly often misleading (this is not related to Python, but to windows dll system). The system may found your dll, but it may be conflicting because of different version : like 64bit vs 32bit ; or because you built one with msvc9 and the other with msvc11/14/... (as it will link to different but conflicting libraries) Dependency walker (http://www.dependencywalker.com/) is nice to identify this kind of things, it will give you what are the dependencies of your python dll and your lib dlls (pyopengl, ...) Actually, you may have installed a wheel not corresponding to your python version or are using a python coming from another source than standard (included version from some softwares are often rebuilt) Hope this will help you.

This should shed some light on using interop assemblies and the functions within them. Download the Dependency Walker (link below), then open up your User32.dll with it. That tool will show you every function within the dll.

Dependency Walker 2.2

I'll answer since the other replies aren't good. What you need to do is have the same number of exported functions. The functions need to have the same calling conventions, parameters and return types. Use dependency walker or IDA. http://www.dependencywalker.com/

Google: proxy dll, wrapper dll

What you're seeing is that msvcp71 failed to load, and the error code returned was file not found. This doesn't mean that msvcp71.dll specifically couldn't be found - it may have needed to load other DLLs that could not be found. Use http://www.dependencywalker.com/ and see what other DLLs are needed by msvcp71.

0xc000007b is a windows error generated when it's trying to execute a mismatching .dll file. Since you're running windows x64 - make sure you have the correct version of visual C++, make sure your microsoft .NET is updated, make sure there's no new updates in the windows update centre. What you're looking for is whether or not you have a x32 or x86 versions of some of these on your 64 bit system which cause the conflicts. If all these are in check I recommend running http://www.dependencywalker.com/ and see if you're not having any missing/corrupted .dll files

I've not used eclipse+minGW so i don't know what options are available.

Another thing to try is run the executable from the commandline. windows may give you a more informative popup error.

Another option is to use 'depends' from <http://www.dependencywalker.com/> which may tell you what it is failing to find ... But this isn't a beginer's tool.

The error suggests it it finding the DLL it is looking for, but the DLL doesn't contain the function it needs. So a versioning problem perhaps. If Windows comes through with a message then google may help

Really hard to say why it won't work if no log file is being generated. Is there anything on your system that would block applications from running? Are you running a 32 or 64 bit OS?

You can try this app to see if your system is lacking any needed files/dll/etc.

http://www.dependencywalker.com/

Use the Profile option to get diagnostics output of the load process.

The first thing I would try is putting both the managed DLL and the native DLL in the /Assets/Plugins folder. Unity handles this folder differently from others, and may be what you need.

Aside from that, I've had issues attempting the same thing. I'm genuinely interested in how you solve the problem.

EDIT: Also, ensure you have all of your dependencies included in the project as well. http://www.dependencywalker.com/

AFAIR extern C will still prefix an underscore.

You can use Dependency Walker to view the functions exported from your DLL.

You can link wiht a .def file to assign an exported name different from the internal name.

pcbnew has a newer rendering engine than eeschema, and it needs:

• Cairo
• OpenGL
• GLEW
• OpenMP

If that problem turns up again, use Dependency Walker to find whether a DLL is missing.

Next steps if the Event Viewer returns nothing:

• Download dependency walker (x86)
  • http://www.dependencywalker.com/depends22_x86.zip
• Extract
• Open depends.exe
• Drag WatchDog.exe onto Depends window
  • WatchDog is located:
    • C:\Program Files (x86)\Frontier\EDLaunch\WatchDog.exe
• Take a screenshot of the bottom half of the window and message me it.

Your executable relies on libstdc++6.dll (and a number of other libraries) and Windows can't find it. Either copy <path_to_rust>\bin\libstdc++6.dll to the location of your binary or add <path_to_rust>\bin to your PATH environment variable.

For a future reference: Search Path Used by Windows to Locate a DLL and Dependency Walker.

If the message went away, moving the dll into the same directory probably fixed that problem. The crash might well be something else. I don't know CodeBlocks but try running the program in a debugger, it should show you where the crash happens.

If you still think it's a problem with dependencies, you can use a a tool like this to see which libraries your program needs to link to.

I fixed it today! Heres is my solution:

Got the problem like many others "Steam says im playing after 2 seks no window opend and to normal Online status"

I tried to start the game in its own folder but an error poped up (Error Code "0xc000007b"). Downloaded &quot;Dependency Walker&quot; <-- Download here. * Open "depends.exe" --> File --> Open --> "C:\Programm Files(x86)\steam\steamapps\common\Metal Gear Solid Ground Zeroes\MgsGroundZeroes"

• wait
• And now you should see something like this!
• the window where you can see all the DLL's look if you can find any x86 dll files (they should be highlighted)
• If you find any go to this site
• Search your dll on the website and download it.
• after that pls copy the dll's in the "C:\Windows\System32" and "C:\Windows\SysWOW64" Folder!
• if windows asks you to replace it... replace it.

Start the game!

Notes: I got no problems by using my G500 Mouse and G930 Headset both from Logitech.(Dirver was also running in the background)

If you have access to a client machine, I would try and run the dependency walker on the application. http://www.dependencywalker.com/

It might be that it is dependent on another version of the .net framework that you may have installed, but may be missing from the client machine.

The other thing to keep in mind is that when you have native code library being loaded, the architecture of the exe is very important. The Any Cpu default is very very bad. I would suggest that the exe is either built as x86 or x64. This should prevent running the application as x64 and loading a library that is x86 only.

A load time dependency could not be resolved. The easiest way to debug this is to use Dependency Walker. Use the Profile option to get diagnostics output of the load process. This will identify the point of failure and should guide you to a solution.

The most common cause of this error is trying to load a 64 bit DLL into a 32 bit process, or vice versa.

http://www.dependencywalker.com/

hope this helps! ;)

Did you check that this are really the only mingw dlls within your path environment variable?

You can ensure if the problem is what i suspect by putting the dependend mingw dlls into the same directory where your ".exe" is. If your application start afterwards its exactly this problem.

You can list the dependencys of your .exe with this free tool dependency walker (http://www.dependencywalker.com)

To be able to help you with your VS related problem please post the complete error message.

Show me one user who has just one or two applications installed.

As I said before, virtually every application is developed with a toolkit nowadays. No sane developer is programming the Win32 API natively today unless he needs to, it's just way too much work.

If it's not Qt they're using, then it's Gtk, MFC or libraries like boost.

There is virtually no software anymore which doesn't need any more than the libraries provided by the operating systems. Just download the Dependency Walker (depends.exe) and pick any executable on your system to check what DLLs it links against.

If the executable isn't working on your own machine, how have you managed to develop the thing? You need to learn about the Windows PATH, about how DLLs work, and about what DLLs are required by your application. You could make a start with that by looking at the application with Dependency Walker.
