I've been having difficulty again on Windows 8.1. ifort setup with Visual Studio 2012 Pro for X64, using command prompt, doesn't retain the path to CL after reboot and so refused to perform a link. I can complete a build combining ICL and ifort by building .obj in the VS2012 cmd prompt and switching over to VS2010 shell prompt to link (I didn't ask for the VS2010 shell setup).
I can run vcvarsall.bat to get 32-bit CL on the path, but don't know an equivalent incantation to get the 64-bit CL.
This may be more of a Microsoft than an Intel tools issue, but surely there is a way to write a script which will put the Microsoft tools required by Intel compilers back on PATH.
I've been through the laborious route of removing all Intel and visual studio tools and re-installing from scratch (about 3 hours when not attempting the on-line installation), but it doesn't reliably fix this.
I attempted to file an IPS support issue but the site isn't responding.
