I think I have a clue on what this is, there are some reports involving a username with long/special characters https://github.com/electron-userland/electron-builder/issues/6865 questions:
- can you run the uninstaller manually in: C:\users\youruser\AppData\Local\Programs\drafft?
- if it fails, can you delete the uninstaller file and try again?
- if it still fails, v2.0.9 uses the old name “drafft” without space, which might be the reason its not working, vould you try that?
Thank you!
