Can't install Vortex to new drive... The drive it was already on died.

[Kanori24]

So the drive I had Vortex installed to died this morning. I went and got a new drive, but when I went to install Vortex onto it, first it says it can't close Vortex (what? I'm trying to INSTALL IT), then apparently tries to run the uninstaller, which is gone with everything else that was on that drive. (E:\ is the dead drive)

 

Trying to 'uninstall' it from Win10's apps list gives the same error about not being able to find Uninstall Vortex.exe, and the mighty Revo Uninstaller (free version, haven't needed it enough to buy it yet) gives a similar error.

 

What else should I try?
