Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
This problem came after 15.0.4569.1508 update on 18.03.2014 and I couldn't resolve it with the recommendations you made so far. I desperately need Office since I am a finance guy. Microsoft need to resolve this issue immediately!!!!!
I am using win 8.1 and Office 2013 pro.
Only Microsoft antivirus and firewall. No other software.
