Corrupt C runtime library?

Question

I'm using Visual Studio Professional 2012 (with Update 2) and since I have a project that needs to be built with the VC++ 2010 toolset I also installed Visual C++ 2010 Express (with SP1).

I use the newer 2012 IDE also for the older projects. So for these projects I set the Platform Toolset to v100. And when I also set the runtime library to /MT or /MTd I get the following error:

error LNK1127: library is corrupt

for libcpmt.lib or libcpmtd.lib, depending on the configuration.

What could be wrong here?

Installation history:

1. VS2012 Professional
2. Windows 7 SDK
3. Uninstalled VS2012 and Windows SDK
4. VC++ 2010 Express
5. VS2012 Professional

Answer 1

If I understood correctly, you installed VS2010 after installing VS2012? If not, please edit your question to make it clear.

This sequence of installations is not recommended by Microsoft, and there are plenty of caveats and ReadMe's to navigate in order to find out what's happened.

I suggest that the best thing to do is to reinstall VS2012 (or do a repair install), then see what - if anything - is still broken.
