Issue

You are prompted to enter your serial number each time you open Adobe Photoshop Lightroom 1.x. After you enter the serial number, Photoshop Lightroom continues to run in Tryout mode.

Reason

If you purchased the Photoshop Lightroom Tryout version, then Photoshop Lightroom must have read/write access to its serial number to update your Tryout serial number to your retail number. Also, if Photoshop Lightroom finds a beta serial number in its registration data, then it prompts you to enter the retail serial number.
