A couple common areas are:
"fatal error c1083: cannot open precompiled header file:
In your vcproj Configuration Settings>C/C++>PrecompiledHeaders you are using the option "Use Precompiled Header (/Yu)" your PCH may have never been created and you should change the option to "Create Precompiled Header (/Yc)"
Now at this point the PCH is being created with each build.
And doing this in a release build configuration may lead to
C4727 warnings, which occur when multiple files are generating PCHs (/Yc)
so you have to go through each file noted by the compiler and switch back to (/Yu)
UPDATE****
in the default configuration you will have stdafx.h & stdafx.cpp (this file is the only one that should have the /Yc option)
