Hi there!
I hope you are doing well and sorry for the trouble you had with Acrobat.
Would you mind sharing more details about the issue you are experiencing with Acrobat?
Are you getting this error message while updating the app or while launching it? Are you on a Mac or Windows machine and what is the version?
If you are on a Mac machine, then please try the solution shared in this article and see if that works for you: https://helpx.adobe.com/acrobat/kb/troubleshoot-activation.html#AcrobatDistiller
If the issue persists, then reboot the machine once, then use Acrobat cleaner tool to remove the installed Acrobat: Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs
Reboot the computer, and install Acrobat: Download Acrobat DC installer for Enterprise term or VIP license
Let us know how it goes and share your observations.
Thanks,
Anand Sri.
