For troubleshooting, you can at least see if the installer will install on a clean computer. Revo is good for a program you uninstall and want to clean up. For this type of program, I would stick with the Windows Program and Features. Whatever installed it (Windows), I would use to uninstall it. Anyway, water under the bridge. Hopefully, they can fix it. If not, there is one person who can....Is it Windows 10? Do you have System Restore on. That would be your best bet. Not as good as a checkpoint on a VM, but....damned good if it works.
That's almost what checkpoints on VMs are for. Set the checkpoint, name it new install, screw up the entire thing, revert to the checkpoint, start over, rinse, repeat....
Don't get me wrong. I don't run all my clients on a VM, lol.
