Acrobat X Pro CS6 - not accepting valid serial number
Hi, I upgraded to a new laptop with Windows 11. The rest of my CS6 works fine, but the Adobe Acrobat X Pro never played. It creates the file but I can't open a pdf. The message is that my trial has run out and when I put in my serial number, nothing happens - ie the process stops and I still can't open pdfs.
I looked into an update - Acrobat Pro 2017 installer - but it says I must uninstall my current version and I'm not even sure if my serial number would be acceptable.
I have uninstalled and reinstalled from the disk. No improvement.
Is there a way to solve this please? Many thanks.
