I have run into this compiler problem following a reinstall of FEFLOW on a brand new PC:
https://connect.microsoft.com/VisualStudio/feedback/details/660584/windows-update-kb2455033-breaks-build-with-missing-ammintrin-h
I've given up on resolving this issue since Microsoft basically states that they won't fix this bug (which only occurs in the Express version of Visual Studio 2010 due to the lack of a x64 compiler which must be added by installing the SDK 7.1).
Will FEFLOW support plug-in development in Visual C++ Express 2012 in the foreseeable future (or does it already)?
Best regards,
Søren
