In "options->intel compilers and libraries->C++ ->compilers", if I set the selected compiler to <Latest> (which is the default), I will receive a `MSB600: Failed to locate: "icl.exe"`. If I choose a specific version in the "selected compiler" list, the error will no longer exist. So, I guess that <Latest> doesn't point to any version and is a broken option.
Thank you for reporting the problem.
Will you please give us your environment details and version details, so that we can cross-check it from our end?
