Got the latest Windows 10 Update Preview Build 16184-170424-2211 this morning and, afterwards,
iLok refuses to work.  Tried starting "Pace Services" and it refused
to start.  Uninstalled and reinstalled iLok, and it still refuses to 
run.  Will post here if I find a solution...

Working fine here with iLok 3.1.6.1793 and Windows 10 Pro 1703 build 15063.168

Good to know...still trying to get it to work here...

Ok...says Preview 1704 Build 16184-170424-2211  so may
be something different...it just installed this
morning, and subsequently, iLok has failed to work...

You can roll back Win10 updates Larry. Maybe that's the quick fix?

Have you checked that the Pace License Service is running Larry?  Try setting it to delayed start, I have had to do that with both my Win 10 machines.

Yep...I even tried to start it manually and it won't even start...
It just says "unable to start start service" after it hangs for a few...

I would roll back, but I've never had a problem before, so, when it
said "do you want to delete the previous version of Windows" I said
yes...as I'm about out of disk space on my C Drive....shame on me...

maybe see if there is an error in the event logs?

Looks like maybe you fast forwarded past 1703 to a preview build somehow ...
