Precompiled header error after updating VS2015

After installing update for VS, when I ty to build solution it throws

2> fatal error C1853: Project.h.pch' precompiled header file is from a previous version of the compiler, or the precompiled header is C++ and you are using it from C (or vice versa)

Hey -

What update for VS are you referring to? Are you unable to compile any project or is this specific to a single project? If you make a 4.11 copy of the project, are you able to compile that with the VS update?

Cheers

‘Update 2’ , but It turns out I just needed to clean up project and then build it
