Dear Philippe,
It seems to me as an environment setting problem with VS. I gave up intel compilers/VS a while ago (in favor of mingw64) and I don't have a working installation, so I may not remember things correctly. However, I do remember that you have to launch the compiling cmd window through a batch file that sets some environmental settings appropriately for 32bit or 64bit compilation.
Are you launching the compilation command through the appropriate batch file? Make sure you have administrative rights (or run it as an administrator).
Edit:
Here is a link to what I am referring to:
Setting the Path and Environment Variables for Command-Line Builds
Best Regards,
Costas
