Running a very good system with XP SP3, 500 Gig disk, 2 Gig Ram
Paint Shop Pro 7 has been working OK for months.
I installed the latest version of Paint Shop Pro Photo X2 and installed three times.
(The progress indicators during setup did not respond smoothly some of the time, although it did say "Installation successful")
When I click on the icon, I get the hour glass working for about six seconds then nothing.
Once that has happened, other programs cease to work and I have to re-boot.
Have repaired XP3 but made no difference.
