Vista 8.03.408b to 8.03.410 - prowin32.exe stops responding

Trying to help a client who lost their server. They purchased a new server, installed Server 2022 and a HyperV running Server 2008R2. They had the original disks for the installation of 8.03.400 but they don’t have the service pack for 8.03.408B…so while attempting to upgrade the recovered database (which in itself has been an adventure), the conversion process window starts and does nothing. Review of the event viewer shows The program prowin32.exe version stopped interacting with Windows and was closed.
Looking for any ideas!

I recall that progress command line programs need to be run in the “ProEnv” (Progress Environment?). Which I think just sets up a bunch DOS environment variables that the programs look for.

That is normally true, but this is happening when I kick off the database conversions from the Epicor Admin login. It is a windows app, but who knows what’s going on under the covers…
