Hello Applepie,
What's the exact message that you are getting?
UAC, it a security notification prompt for you to approve before Windows allows a program (ex: PSP 8) to
Run as administrator (elevated). You could set the
UAC notification settings to "Never notify" to turn off UAC and not get anymore UAC prompts, but that would lower the security of your entire system.
If you are getting a "Open File - Security Warning" notice, then see if the tutorial below may help.
Open File - Security Warning : Unblock File
Hope this helps for now,
Shawn
