I had 3.4 alpha installed. Uninstalled it, downloaded this, and when I run this it starts 3.4 alpha again. I used task manager to find the location of the executable it's running and it's in the appdata folder. So I deleted that and ran the downloaded 3.3.1 again and the 3.4 alpha starts up again and reappears in appdata. What do? edit: there's nothing in my usual install location other than temps of old builds. When I was running 3.4 alpha, every time I started it, it would show me the install setup. Now every time I have tried to run 3.3.1 beta it just goes straight to 3.4 alpha, no install screens.
