The wallet here (https://support.supernet.org/support/solutions/articles/29000013936-installing-and-using-agama-for-the-first-time-on-windows-and-updating-gui-) is the latest version for Windows and running it in native mode is the most stable, there is no other wallet I am aware of that I can suggest as an earlier version worked for me, but then stopped.

All I can suggest is that you remove everything and restart your pc to make sure it is gone and then try to reinstall again... windows can be finnicky with this stuff and leave files lying around.

The best idea is to join the supernet slack (http://slackinvite.supernet.org/) and see if someone can help you in real-time.
