If you are installing E14 you need the serial number of Elements 14 and not the one E11.
Since the install program should be able to look up my serial number of elements 11 connected to my adobe id, it should work.
No that is not how it works. You have to enter the serial number.
I purchased the upgrade version of elements 14 via Amazon, but the box was delivered without any serial number. There is a sticker on the box saying (translated):"Upgrade from a previous version of Adobe Premiere Elements. This Upgrade-version only applies for licensed user of a previous version of Adobe Premiere Elements."
I only have a serial number of premiere elements 11. So, where can I get the serial number for that upgrade edition?
You need a E14 serial to get this working.
Mabybe the serial was send in an email.
Or this upgrade only works with E13
Get in touch with the vendor on Amazon.
