I'm sorry for the frustration.
We know that some users have entered this state by way of an update partially failing (some of the files get updated; some don't because they are locked). We think we've figured out why that happens in most cases and will have a fix soon. To get back into a stable state,
- Restart your machine
- Go to the Start Menu and Choose ProSeries 2020 -> Tools Repair Updates
If you've done that and it's still failing, then we need help isolating why this is happening.
If you get a dialog titled "ProSeries Crash Feedback", just enter "For Orlando" from your userId here, provide as much detail as you can in terms of what you where doing at the time it shut down and submit.
If it's just shutting down without any dialog, reopen ProSeries, choose Help -> Send Logs, and email the resulting .zip file (saved to your desktop) to email@example.com. Then we'll provide further questions and instructions there.
