Update Proseries 2019

I know Ive seen that error before, and when I google it, I can see this one link that is suppose to contain that error, however when I click the link, theres no mention of it.     @IntuitBettyJo  or @IntuitAustin can you dig up some info on this one?

ProSeries 2019 DOES have an update repair tool, whether that might help or not, Im not sure.

Same Problem

Reinstalling Workstation did not work

Ran Updates and Repair Updates 5 times

Program still won't open

If you see me reply above and get the same error message, here is an approach

All workstations worked fine but Server/Workstation failed after allowing updates. Earlier updates worked fine. The program works fine except for 2019 Product Updater. Previous years all work fine.

Problem in this case was a silent update of a new feature in Backup program which is some sort of malware detector. Only ProSeries 2019, not any earlier years, caused the updater app to fail.

Boot into Safe Mode with Networking (So you can log into ProConnect)

Run the stand alone ProSeries Update applet from ProSeries 2109 program group. If it works then

use normal troubleshooting process to identify the culprit
