Virtually every time I initiate a Word-to-PDF conversion from within Word, I get this error message. I have had CC since its inception, and I have had Acrobat Professional licenses going back to about version 4,5, or 6.

I have signed in and out of CC more times that I can possibly remember. I have uninstalled and reinstalled Acrobat more times than I care to admit. Yet this keeps happening, practically on a daily basis.

What is going on? How do I fix this? Am I the only one with this problem?

This worked for me (Windows). Don't know how long.

But in my case step 1) the SLStore folder location is:
%appdata%\Adobe\SLData\

May 2022, still a thing. Why do I pay $40 dollars a month for this?

2023 Update for Outlook 365 / Creative Cloud: Same issue as above, Acrobat was activated but Outlook plugin always gave the same error. I didn't have Acrotray.exe running in Task Manager, but found that terminating the "Acrobat Licensing Service" fixed the issue.
