Starting Paint Shop Pro 4 as a non-admin user under Windows XP yields the following message:
Failed to update the system registry,please try using REGEDIT.
Apparently similar results are experienced under Vista (because UAC essentially equates to running as a non-admin user).
The problem is fixed under PSP 12 -- but that doesn't help you if you're running an older version.
The problem arises because PSP tries to update a couple of registry entries in the system registry. You can fix it by simply granting "Full control" to the Users group for the following registry keys:
- Start regedit
- Navigate to the key
- Right click the key, click "Permissions..."
- Add Users if it's not already there.
- Tick "Full control"
- Click "Advanced"
- Tick "Replace permissions on all child objects".
Repeat for each key above.
