On my machine I have been working with IVF 11.072 and 12.0, both integrated in VS2008 and VS2010. Recently, I installed VS2013 and Intel Parallel Studio XE 2013. Since with the first two I was able to change (if needed) the compiler from Tools->Options->Intel Composer XE->Visual Fortran, I hope to maintain the three different versions of the compiler. However, now, all three Visual Studio versions are integrated only with the 14.0.
Since I am dealing with the update of academic legacy codes, I would prefer to maintain the three of them in each visual studio version. I found this blog post (https://software.intel.com/en-us/articles/using-older-intel-visual-fortran-versions-in-different-microsoft-visual-studio-versions) but it relates only with the possibility of having an older version. I understand that I have in some way to change the integration folder C:\Program Files (x86)\Microsoft Visual Studio 9.0\Intel Fortran, but I do not know how. Even with uninstalling and reinstalling everything it did not change much.
Is still possible to have multiple versions? if yes, how can I do it?
