What is the computer operating system? For now I will assume Windows 7, 8, or 8.1 64 bit.
In order for the product activation to occur you need to insert the serial number, not the product number, during the installation of the program or whenever it is asked for in the process. Do you have the purchased serial number and are you using it? Are you getting a message specially Invalid Serial Number?
The serial number is not on the disc if you are installing the Premiere Elements program from an installation disc, nor is it on the envelope in which the disc is stored. Typically it is on a label on the box that houses the discs in their envelopes. This is what I have always found when I was using a Premiere Elements Installation disc purchased in the boxed packaging.
Please review and consider and supply more details.
