"The Application was unable to start correctly (0xc000007b). Click OK to close the application" when starting Visual Studio 2010

Question

Hi,

Visual studio 2010 on my machine is giving me an error"The application was unable to install correctly (0xc000007b). Click OK to close the application". VS has been working fine on my machine for almost half an year without any problem. I haven't changed anything on my machine like install software or anything and suddenly I a m getting this error. 

I did a lot of search on internet and haven't found anything that could solve the problem.Operating system on my machine is windows 7.

So far I have done following things to resolve the problem.

1. Installed VS2010 several times after the clean uninstall.
2. Loaded the devenv.exe in the dependency walker and it is highlighting "MSVCR100.dll" as 64bit instead of 32 bit and the file is located C:\Winsdows\system32.  Tried to replaced the file with 32bit version using ubuntu but its still giving me the same error.
3. Checked the event log and it shows lots of windows update. The only one update that shown as failed is  "KB958488-v6001-x64.msu" that I have downloaded and installed manually and still VS 2010 is not working.
4. I used the process monitor but I am not really good in using it to analyze the cause of problem but it does show lots of name not found error.

Any help to understand what the problem is and how can I fix it without reinstalling windows will be great.

Hi Gfazil,

Welcome to the MSDN forum.

From your error 0xc000007b I found that the error means "STATUS_INVALID_IMAGE_FORMAT" which means Bad Image. I have a guess that your disk need to be fix so I suggest you do a disk check before other steps. But it may needs a very long time.

After repair of your DISK if you still have this kind of problem, please feel free to let me know.

Best regards,

Hi Barry,

Thanks for your reply.

I did try to repair the drive but its still not working. I think I will go for a re image on my machine.

Thanks a lot for your help.

Hi Barry,

ReImage does solve the problem. I recently found a solution that doesn't require reimage.

The problem was due to 32/64-bit mismatches of various system dlls required by Visual studio. Somehow the dlls it needs got replaced by 64-bit versions that it couldn’t load.

Replacing the dlls mentioned below from a machine that is working solves the problem:

c:\Windows\SysWOW64\msvcp100.dll
c:\Windows\SysWOW64\msvcp100d.dll
c:\Windows\SysWOW64\msvcr100.dll
c:\Windows\SysWOW64\msvcr100_clr0400.dll
c:\Windows\SysWOW64\msvcr100d.dll

Thanks

Answer 6

Hi,

Do you have access to another machine that's working properly?

If yes, then just copy the files from that machine to yours and launch VS and it will work.

I hope it helps.

Hi Gfazil,

I got the same  error 0x000007b when I wanted to call Matlab Engine in my C code.

However I did get your solution. My system is win7 32bit, and I'm quite confused with how to replace the dll files you mentioned above.

Could you specify a little bit, like to replace them with some other dll files?

Thank you very much.

Answer 8

Hi Emily,

I received this error for Visual studio and the files mentioned are visual studio files.

I don't think so that you have the same issue.

"0x000007B INACCESSIBLE_BOOT_DEVICE" error message is a generic error message and the solution varies from problem to problem. 

May be a search on Google for 0x000007b related to MATLAB may be more helpful. 

Sorry I couldn't be of more help. I hope you find the solution soon.

Regards
