You can always find the latest (full trial) version of PhotoPerfect on our download page at:
Arcadia Software -*Download
After installing please just start it and select the "Help -> Enter license code" menu option. Please then enter your license to activate PhotoPerfect and all extensions of the corresponding edition you purchased. In your case it would be RGBMax, YMax, Xe847 ProPlus, Perfectly Clear and i2e.
Additionally I have just sent you detailed instructions to your email address.
Hope this helps.
