error TRK0005: Failed to locate: "icl.exe". The system cannot find the file specified.

I had just my machine rebuilt, because I could not update the intel software tools.

I installed the parallel studio XE 2017 (basic)

I am using win7, 64bit with VS2010, VS2013 and VS2015.

I received the error:

"error TRK0005: Failed to locate: "icl.exe". The system cannot find the file specified."

in VS2015 (debug, 64bit)

After reading on the web about possible path shortening (a well-known windows artifact, that there was no way to be anticipated or worked-around- I presume!), I decided to fire-up devenv.exe from the command prompt of PSXE 2017, which worked fine!

Now, I would like to be able to not have to go through this every time I start Visual Studio.

There is a bunch of locations in which icl.exe resides:

C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017.0.109\windows\bin\intel64_ia32

C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017.0.109\windows\bin\intel64

and :

C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017.0.109\windows\bin\ia32

which one should I use? It seems -I wish- the first is a wrapper for the other two. Is this correct?

TIA,

Petros
