Windows 7 64 bits - tester required

[Antonio Linares]

It seems as the Windows error 0xc000007b is quite popular and could be related to a virus.

Not sure yet, searching and reading on google

Anyhow to double check it just in case:

We use Microsoft Security Essentials properly updated, but who knows...

It may be a good advise if you also run this tool on your computers.

It seems as it may also be related with not having the most recent .NET installed (we don't use .NET from our EXE, but...).

Please try to install the most recent .NET for your Windows 64, thanks

This seems to have more sense:

Error code 0xc000007b means INVALID_IMAGE_FORMAT (ntstatus.h) which indicates that the the application or some dlls are not valid Windows images.

Alina has provided good suggestion to diagnose the issue. To trouble shoot the issue, I also suggest you get a version of Debugging Tools For Windows or a Userdump.exe, because we could use them to generate a dump file and then analyze it.

Hello Antonio,

does a test on a 2008 SERVER be useful too?
Best regards,
Otto

Dear Otto,

If it is 64 bits then yes

BTW, I got your mail with the WinHotel magazine. Many thanks and congratulations!

Hello Antonio,

WINDOWS SERVER 2008 R2 Enterprise 64 Bit

Error:
MSVCR100.dll missing.

Best regards,

Antonio,
should I try to insert MSVCR100.dll to System32 or should I wait for another test-exe.

Best regards,
Otto

Problem solved!

We were using a wrong resources manifest file. Now it is ok.

Here you can test the EXEs again:
