In Windows NT, you don't have to install into "c:\winnt\". You could be in "g:\blerg\ooh\" instead. Thus to locate where to copy the files for installation is dependant on this location. Instead search for "\\machine_name\?\*\system32" as the "system32" must exist on NT & it's derivatives. Indeed attempt to get the "%SYSTEMROOT%" environment variable off the remote machine, to directly give the location.
