Illustrator CC crashes on every start after 2017.0.1 update
Crashes on boot when initializing illustrator.exe.
Diagnostics don't finish (currently at "Diagnostic Test 44"), startup screen disappears and the next time I try to launch I get this box:

Only change was I installed the Illustrator update first thing this morning from Creative Cloud.
I have tried deleting and reinstalling and rebooting.
Windows 7 Enterprise, Service Pack 1, 64-bit
Illustrator CC 2017 2017.0.1
