The step "In the Mathematica 5.1 installation directory..." is a bit of a problem for those of us who downloaded the Windows installer for Mathematica 5.1: It's just an .exe file, not a zip file. So how would we find that directory, which must be a fleeting, temporary one (under the installing user's "Documents and Settings" "Local Settings" Temp directory?) that is created when one runs that .exe file and then surely erased ?
