If you're having difficulty installing Photoshop Elements, try the following.
Photoshop Elements 8.0 requires a Muliticore Intel Processor, which your Mac Mini may not have.
To check which processor your Mac computer has, do the following.
1) Open Finder.
2) In the Apple menu, select About This Mac.
3) Look at the Processor line to see which kind of processor is in your Mac.
Before installing software, close all other programs, including fire wall and anti-virus programs.
Sometimes the installer doesn't launch.
Locate installer.exe on the installation disc, and double click it.
• Write down the exact wording of any error messages.
• Have the serial number for the program.
Go to Serial Numbers.
Call your computer manufacturer, especially if you paid for a support plan.
