Attempt to downgrade failed

I set up WinSCP NOT to upgrade. You pushed an upgrade anyway. So I tried to downgrade to the previous version and am getting an error. (Attached)

Please give us more details. How did you "set up WinSCP NOT to upgrade"? How did we "pushed an upgrade"? Is this about MSI installation?

Yes, it is about an MSI installation. On 2/15/24 you pushed an upgrade even though I set up my WinSCP installation to never upgrade.

The MSI is failing to complete an uninstall, errors 2753

Uninstall error with MSI installer for v6.3

You didn't answer all of my questions.
We do NOT push any MSI upgrades. The official WinSCP MSI installation does not upgrade automatically anyhow, ever.
Maybe it's the organization that manages your computer that does it.
