Not sure what you mean. Please clarify.
Photoshop Elements 9 does not need a personal URL in order for it to be installed. Once the program has been installed it automatically connects to www.photoshop.com(you may or may not want to setup an account here) and backs up your photos(creating an account on Photoshop.com needs a personal URL which can be provided to friends and family if you do decide to share photos or videos with them)..
You also may want to refer to this doc for more help on PSE 9.
If you purchased the boxed product you will need the original disk.
If you purchased from the Adobe on-line store a download may still be possible.
