Hello mate,

You get this error when 64 bit application is trying to run 32 bit .dll;

To resolve replace mfc100.dll, mfc100u.dll, msvcr100.dll, msvcp100.dll files at your C:\Windows\System32 folder with 64 bit versions.

They can be found here - http://www.bitdefender.com/files/KnowledgeBase/file/dlls_x64.zip

Regards.

Hey i just wanted to thank you! I somehow must've installed something that messed with these files as unity that worked before, stopped working and crashed on startup with the error that OP also posted. Your solution worked flawlessly! Thanks man!
