Welcome to the forums. Assuming you're running icl.exe from the command line, can you do a "set INTEL_LMD_DEBUG=1" before the call to icl.exe, then run icl.exe and copy the output from running the command until it hangs here? Thanks!
Thanks for the response.
Unfortunately, on the affected system, after setting that environment variable, icl still produces no output. I've tried it under both a vanilla command prompt and also both the 32 and 64bit command prompt windows from the parallel studio start menu item. Any other possibilities?
