From whom did you purchased Premiere Elements 12? What computer operating system?
On how many computers do you presently have your purchased serial number installed?
Is this the first time you are using that particular Premiere Elements 12 purchase on any computer?
Please give more details.

This is not Adobe. Do not post purchased serial numbers or private information in this forum since it is a public forum. It compromises your information.
I have asked a moderator to help you remove the private information that you have posted.
Premiere Elements 12 Mac and 14 Mac are standalone versions.
Just in case mention...
If you go to Premiere Elements 14 Mac, you will need to purchase that product to get new serial numbers. You cannot use the Premiere Elements 12 Mac serial numbers in Premiere Elements 14 Mac.
Premiere Elements 12 and 14 are not listed in Adobe as being supported by 10.11, but there are many who report that at least 13 and 14 have worked for them on Mac 10.11. With the Mac, can you go back to the previous operating system to confirm that Premiere Elements 12 Mac still works there?
To be continued....
