Norton Password Manager and Vista

I've been using NPM for a quite a while and like that it works with
non-webpage programs (such as Quicken). In trying to install it from my
SystemWorks 2006 package it says the setup program is incompatible. If I try
to run the NPM install from within a folder in the CD, it asks for a 24-digit
code in groups of 4 but that's not the same as the main setup's code in
groups of 5. So I can't find any way to just install NPM. I've about given
up on Symantec products anyway but I'd still like to find a good password
manager for Vista. I know about RoboForm but it only seems to work with web
pages. Anyone have any ideas on how to install NPM on Vista or a good
replacement? Thanks!
