What computer operating system is involved?
If your problem is the Premiere Elements 7 will not start for technical reasons, then Adobe is not going to help you. The program not starting can be caused by several technical issues, and Adobe does not support older versions and has limited technical support for even the current version.
If the non start means that you cannot install the program - too many Premiere Elements 7 using your purchased activated serial number - Adobe
may be able to help you but.....first have you done the following?
Do you already have 2 computers with the same purchased activated serial number and are you now trying to get that same purchased serial number
on a third computer? If so, then the answer is to uninstall Premiere Elements from one of the two with the serial number so that you can get Premiere Elements 7 on the third computer. Adobe allows you to have the purchased activated serial number on no more than 2 of your computers.
