At least when I launch, I can tell it to not install the update. This symptom has happened before on several occasions when there are new updates.

I have tried run as admin (though my login is admin).
main computer Lenovo k430 - latest updates for win10 installed. As mentioned, at least I can run my software without the update this time, so not dead in the water (on this computer). It is a bit disappointing that this keeps happening, though...
