Adobe Acrobat Pro 10 TLP License invalid

Hi,

I have a Acrobat Prpo 10 TLP Volume License.

After changing my Windows 10 PC to a new Windows 11 PC my License is no longer accepted. I can install the software, but at the first start I get the message that the License No. is invalid and it switches to a demo version. When I re-enter the License No. I get the information that the No. is invalid.

Adobe 10 is out of Support, but I don't want to switch to a subscription. Has anybody a solution how to fix thsi license error?

Thank you in advance.

Michael
