Thx tim, but as wrote, I even repaired (it's an option in the installer) my intel parallel studio 2017 cluster edition installation, without success.
What do you mean by "If the new vs and c++are visible" ?
Because when I uninstalled intel parallel studio 2017 cluster edition and reinstalled it, my visual studio 2015 was visisble indeed whereas it wasn't when I simply (and normally) choosed to repair/modify intel parallel studio 2017.
What's the exact file name of your "setup.exe" in parallel studio 2017? I just tried the "Modify" option using w_mkl_2017.0.109_online.exe installer, it allows me to "Choose Integration Target", where you have options to choose VS 2013 or VS 2015. Now seems you have parallel studio 2017 installed again, you may try to Modify and see if the same issue exist. Thanks!
