Acrobat Standard XI crashing shortly after launch

[robsons1995]

the issue started today, window 10 PCs, Adobe XI launches then closes within a few seconds. 

Anyone else experienced this today? Wondering if its a Microsoft or Adobe update.

I only loaded the free Acrobat Reader on the same Win 10 Pro machine as my
Acrobat Pro XI.
I made the Acrobat Pro XI my default program for .pdf files in Windows Apps
settings.
The crash problem went away. Nothing else worked.
