I have installed Acrobat 2020, and it is still valid til december 1st, however the services can't be used as its stating with Expired. Help!

It seems like the license is still valid, but Acrobat is incorrectly showing an expired message. Hopefully, there’s a simple way to refresh the license or resolve the activation issue.

​@Dreamy_glamour5CCF I saw an Adobe employee on a different post, if users are having issues installing to post the comment in the Download and Install: https://community.adobe.com/download-install-615

It does sound like you have a perpetual license, mak sure you activate it using the correct installer, not Creative Cloud.
