I’ve been working a lot lately on the Launcher, and currently trying to fix the last bugs with the updater part.
You can try with the new version now to update, so far I only had problems, if the update was pretty big.
In that case, the launcher will only get a part of the Update, Just run it again that should be fine until the file hashes match.
This version now is only a test push.
Expect more updates in the next days.
