Veeam B&R has been running on this server for years and has been upgraded from 10 > 11 > 12, and now to 12.1. Never an issue until the 12.1 upgrade failed. During the upgrade, I received some type of message about SHA encryption (I wish I took a screenshot...), and then within a few minutes after that, it failed outright leaving a corrupted installation (no means of rolling back.)
I have no issues doing a complete uninstall of Veeam and a re-install, however I want to make sure that I can re-import their job history, etc. and the loss is minimal (or zero.) - I just don't know if Veeam is in a state where it can be uninstalled due its current state.
Here's a screenshot from my Windows Services panel:

I created a support ticket (03164286) - Waiting for someone to get back to me.
