When starting the SourceTree setup a small window is opening and closing again after less than a second. Although I am not able to go through the setup I get a 55Mb folder at AppData\Local\SourceTree including a SourceTree.exe . When opening this one nothing is happening. Both .exe files won't do something else when run as admin. I have already tried uninstalling, deleting the app data folders, restarting my computer, restarting the setup. Nothing happens. Hope that someone knows a way to fix this.
