Has anyone had luck installing just NAV 2003 off the Norton Systemworks Pro 2003 CD?

All 5 machines I've tried it on (XP, w2k, 98) after the install I'd get a error message similar to "Internal program error, uninstall and reinstall NAV".

On one of the w2k machines, after uninstalling and reinstalling a few times I finally got it to refuse to boot. (I always ghost before installing anything Norton)

I finally tried installing the entire NSW's package on a 98 machine. Everything works fine. NAV included. So the 98 owner got the whole 9 yards whether he wanted it or not.

The only reason I buy the NSW pro CDs is it's so cheap. And all I want for myself and the machines at work is Ghost and NAV.

Has anyone found a trick to circumvent the necessity of installing the whole shebang?

All progs could be installed separately up to and including NSW Pro 2002.

TIA
