I think that was asked many-many times in the past but this time, after reading Intel Parallel Studio XE 2016 installation requirements, I'd like to address the problem again.
Could we have Standalone, that is without Microsoft Visual Studio but with some Platform SDK, installations of latest versions of Intel C++ compiler?
We clearly see that Intel and Microsoft have a "Greedy Deal" and that is why new versions of Intel C++ compilers can't be installed without Microsoft Visual Studios and now a list of prohibited Visual Studios includes very good and stable Visual Studios 2005 and 2008 Professional Editions ( PE ), and even Visual Studios 2010.
This is Not going to work for many of us!
I would forget about VS 2005 PE but VS 2008 PE is about 8 years old. I don't see any technical reasons why Intel stopped supporting it. It is clearly a Money Matter.
Intel doesn't want to provide Standalone installations for latest versions C++ compilers and I think some loyal to Intel C++ compiler companies, especially small, could start dropping support of it in favour of Open Source C++ compilers like MinGW and Watcom.
