I am getting the notorious \"Error C1902: Program database manager mismatch; please check your installation\" in my VC++ builds in Visual Studio 2010. My VS will not even build
I had the same error, and the problem was that the "mspdbcore.dll" file was deleted from my \Microsoft Visual Studio 12.0\Common7\IDE\ folder. This post helped me solving my issue.
PS:The deletion was made by a "duplicate files cleaner" utility.
