Word (Office 365) integration broken

Yesterday morning Acrobat updated (I have an Acrobat Pro susbcription) after the update the word (and all other office like excel) integrations were no longer available. No Menu entries or Adobe entry in thr ribbon.

I tried what I found on https://helpx.adobe.com/ch_de/acrobat/kb/troubleshoot-acrobat-pdfmaker-problems-office.html (followed all steps, com add-in is enabled), restarted word/windows...

I can still do a save as pdf, but all other conversions and menus disappeared.

I even downloaded and re-installed Acrobat - also no change.

Is there an issue with the latest version or any other steps I can try to resolve the issue

Thanks- Peter
