I'm trying to package Unison (not really my program) into an easy to use installer. Tl;dr: a screenshot.
When I install and run it on the test machine, it says This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix the problem.
The event log reveals that it can't find Dependent Assembly Microsoft.VC90.CRT.
Search reveals that the "missing" dll is in fact in C:\Windows\WinSxS
So what's wrong?

we made one application on Visual Studio 2008 , it about to release. but now we are getting the crash while launching the application . could you please any give a suggestion how do i debug on this particular issue
You can run the Release build in the debugger, too. Turn on debug-info settings in both the compiler and linker tabs (I think that was not the default in vs2008 and there were two distinct places to set) but don't change any optimization options or other setting.
Then launch the program from the debugger. If the resulting EXE shows the crash when run normally but not when started via the debugger, there are more things to make the situations work the same (and that shows clues as to what is wrong, too). So let us know if that still doesn't reproduce.
There could be a lot of reasons for your application's Release is crashing.
Did you link proper Release libraries with your application in Visual Studio project configuration ?
Check your code for some missing Release specific code.
My best guess is you are not linking to proper libraries for the Release version of your application.
Also, one reason could be that your application may be trying to load some file that may not exist. This happens with me sometimes when my Release build of application does not find file that it needs (Eg: OpenGL application trying to load a shader file that is missing); and you don't check for errors.
when i try to run a application developed in vc++ on windows7,i get popup window saying that"the program can not be started because MSVCR80D.dll is missing from your computer,try reinstalling the program to fix this issue."
I googled it,it says that this DDL may not be present in your system or it has been got corrupted,Now i searched this file, i get this file at 20 different folder in win7.
I am not getting which file has been corrupted or if it is missing then where it is mising?
can anybody tell in which folder ,this DDL is missing or might be corrupted?
Thanks in advance. .
You're trying to run a Debug version of your program on a machine which does not have VS installed. The MS*D.dll files are not redistributable - they are installed were VS is installed. If you want to run executables on other machines, compile them as Release. You might still need to deploy some files (depending on how you're linking to the CRT), but that won't be a problem.
Never ever distribute your DEBUG builds to customers. Always distribute Release build.
Yes, of course, in develoment environment having multiple machines, you may share Debug builds to other developers - provided others developers have debugging-tools (like VS) installed on their system along with Debug-binaries of shared DLLs (like MSVCRxx).
Are you using the same computer that compiled the program? If not, you need visual studio redistributable files to run it.
Search the internet for your version of visual studio or visual c++ redist, you'll find it.
Unfortunately this is going to be a pretty open-ended question, but I am at my wit's ends and I thought I would reach out for some advice.
This is a Visual C++ MFC app using Visual Studio 2008 SP1.
A coworker and I both had Office 2007 installed and we have both had strange DLL loading problems with our app since. Specifically, LoadLibrary is failing to load one our DLLs ( the first one it loads ) and returning error code 126 ( module not found ). What's really strange is that if I just run the executable from the windows explorer it works fine.
I took the usual steps to diagnose the problems:
Verify that the file existed and that the current working directory was pointed at it.
Run dependency walker and verify that it's dependencies are loading correctly. They are all loading ok except the ones this question says are ok to fail.
Experiment with loading some different DLLs at the same location in the code. Some of the simple 'stub' dlls succeed, but most of them fail.
Experiment with loading the DLLs that are failing from separate test apps - in an empty console app and a barebone MFC app, all the DLLs are loading fine!
Try to load the DLLs with LoadLibraryEx and the LOAD_LIBRARY_AS_DATAFILE flag, which does succeed but doesn't get us very far except to point out it's probably a dependency problem.
I really don't know what else to do at this point. Like I said, Office 2007 is a common thread in our problem but I don't know what kind of problems it could create. I really don't know even what steps to take next. Any ideas?
edit: I'm pretty sure the current working directory is not in the DLL path for some reason. It seems the DLLs that are failing are ones that need any other DLLs. If I turn on Loader Snaps debug output the current working directory does not appear to be in the DLL loading path. Any idea what could cause this?
edit2: The current build dumped the executable into a directory other than the working directory. For some reason, when I tried to load a DLL which then tried to load ANOTHER DLL, the current working directory is no longer searched. By putting the executable into the directory with all of the DLLs I am trying to load, the problems go away. Based on all of this, and the output by loader snaps, I am 98% sure this is some bizarre Visual Studio bug and I will simply have to work around it.
Office 2007 turns on SafeDllSearchMode in the registry.
http://msdn.microsoft.com/en-us/library/ms682586%28VS.85%29.aspx
With SafeDlLSearchMode, the current directory is no longer searched. To disable it, they claim you can go into regedit and set HKLM/System/CurrentControlSet/Control/SessionManager/SafeDllSearchMode to 0, but this did not work for me. Calling SetDllDirectory to the current directory DID work for me, although this only works if you are targeting XP SP1+.
The reason this caused problems in my specific app is that when we run the executable from the debugger, we keep the executable in a different directory than the current directory with all the other build files. When we run outside of Visual Studio, we first copy the executable into the directory with all of the other DLLs. The directory that the original executable is called from is ALWAYS in the search path, so if you keep your executable and your dlls together, you would never run into this problem.
Still, it's quite confusing for Microsoft to change the dll search path under us like this.
Does the DLL which fails has MSVCRT80 in dependencies? If yes, the most likely reason is that Office 2007 has overridden MSVCR80.dll
We have an installer application.
In that we have one dll related to our application.
We created setup with all respective files.
We used "Install Shield 6.3" and created a setup file.
After created build. The build is working in xp, not working in 2000.
It is showing error message as Couldn't load .dll only in win2000.
What could be the issue any idea?

It looks like one of the system/third party dll you are loading is either not available or of wrong version. Use a tool like dependency walker to check whether all the required dlls are available or not.
You have probbely missing prequsits that exits on XP but not on Win2000.
You need to run the Dependency Walker tool on Win2000 and load the problematic DLL, the tool will tell what is missing.
Try running installation with Filemon in the background, filtering with the missing DLL's name. Then, see where the DLL is searched for, and fix the problem. Hard to say without any further information, but first difference I have in mind is that the system folder in XP is C:\windows\system32, while in win2000 it is C:\winnt\system32. If you've hardcoded the system path for any reason, it might be the problem.
This is the error Dependency Walker gives me on an executable that I am building with VC++ 2005 Express Edition. When trying to run the .exe, I get:
This application has failed to start because the application configuration
is incorrect. Reinstalling the application may fix this problem.
(I am new to the manifest/SxS/etc. way of doing things post VC++ 2003.)
EDIT:
I am running on the same machine I am building the .exe with. In Event Viewer, I have the unhelpful:
Faulting application blah.exe, version 0.0.0.0, faulting module blah.exe,
version 0.0.0.0, fault address 0x004239b0.
Open the properties sheet for your project, go to the Configuration Properties -> C/C++ -> Code Generation page, and change the Runtime Library selection to /MT or /MTd so that your project does not use the DLL runtime libraries.
The C/C++ DLL runtimes used by VS2003 and up are not automatically distributed with the latest version of the OS and are a real pain to install and get working without this kind of problem. statically link the c-runtime and just avoid the total mess that is manifests and version specific runtime dlls.
I've had this problem. The solution has two steps:
1. Compile your program in "Release" mode instead of "Debug" mode (there's usually a combo-box in the toolbar)
2. Download from Microsoft their Redistributable Package of runtime components. Make sure to download the x86 edition for 32-bit computers and the x64 edition for 64-bit computers/OSes. Install this package on the target computer, and your application should run fine
P.S. This is a SxS thing
P.P.S. Alternatively, use a different compiler (like GCC, for example with Dev-Cpp) to compile your program's source, and your headaches will disappear.
Sorry to bump an old question, but I was able to get around this exact issue and thought I'd post a solution in case someone else needs it...
Even after installing Microsoft's redistributable DLLs I was getting this error, the fix was to copy the
C:\Program Files\Microsoft Visual Studio 8\VC\redist\x86\Microsoft.VC80.CRT
folder into the application's directory on the target PC. After that, no more problems.
BTW, the DLL that was giving me issues was a 3rd-party DLL that had never had problems before on over 100 other computers... go figure.
Run Event Viewer: it'll have more information.
Probably you've attempted to run your program on a machine that doesn't have the VC redistributables installed, or you're attempting to run a debug build on a machine that doesn't have Visual Studio installed (the debug libraries aren't redistributable).
I have had the same issue with VS 2008-built debug binaries on other winxp sp3 machines.
I first tried installing the client machine with vc redist package,as it seemed sensible. Annoyingly, it didn't work.
I tried copying all the dependent dlls to the application's directory - still didn't work
After being struck over this issue for hours, I found that the latest VS builds require manifests and policies to link with the dlls. After copying them into their respective "C:\WINDOWS\WinSxS\" folders, I got it working.
The problem was caused due to the fact that the vc redist package did not install debug versions of dlls, they somehow thought its up to the programmer to figure out.
