--- Comment #28 from sworddragon2@aol.com 2012-10-19 04:36:41 CDT --- I have tested this now again with the newest git but after the instllation window appears (the one which is flickering black without -dx9single) it will hide instantly. It is still in my panel but I'm not able to recover it anymore. This means it is currently impossible to install Guild Wars 2. Has somebody the same problem?
