OS 10.11.2/Parallels 11.1.2/Windows 7/Office for Windows 2016 Issue

I was running OS 10.11.2 / Parallels11.1.2 / Windows 7 and Office for Windows 2010 and everything worked fine.

I wanted some of the newer features of Office for Windows 2016 so upgraded from 2010 to 2016 and now have a problem. The three key Office for Windows 2016 applications I use -- Excel, Outlook and Word -- freeze (i.e. the area above the menu bar read "Not Responding") forcing me into task manager to shut down the application. The freezing problem is so bad / frequent that the applications are unusable.

I would appreciate any insight / solutions people have to fix this problem.

Thanks!

 

Appreciate the suggestions and in response note:

1. I have looked at event viewer and I do not see anything helpful (admittedly, I am not very familiar with event viewer); and

2. I did not an uninstall and reinstall but to no avail.

Thx.

 

Yeah, I thought of that but it really does not help me either identify or solve the problem as I need to get Office 2016 working within my current VM which runs my other Windows programs...
