It looks like version 7.3.657 automatically fixed this issue and finally updated my PC!!! Yay!
I'm glad to hear that, @tnwheeler, but a bit perplexed. 7.3.657 is the same version you were previously attempting to install. I don't suppose you're aware of anything else in your computing environment that changed recently?
As far as I know nothing changed.
Weird, but hey, glad it works now!
We are improving our installer for the next update, it should be more resilient.
Just wanted to confirm that the .661 to .684 update appears to have happened in the background without any issues.
Awesome! Thanks for letting us know.
