Windows Installer Problems/Stall Solution Error 2769

I've just gone through the better part of a day trying to resolve the
windows installer stalling out for Postgresql version 8.2.5

DEBUG: Error 2769:

The faq mentions a cygwin path problem, but I did not have cygwin
installed. I tried turning off all antiv-virus, firewalls and
reconfiguring registry and still it would not work. Finally I
temporarily removed my whole path (anti-virus and firewall were not
turned off), issued Path from command line and tried the msi installer
again - voila, the installation worked! There is probably something
suspect with my PATH but that is another issue.

Hope this helps others avoid this frustration.

Cheers
