Why did this post get moved to "DX11 Crash issue"?? This is not a DX11 issue. The launcher does not even get to the log in stage. I can't image this has anything to do with DX11. In fact, now the installer doesn't even get to the install stage.
Tried everything on this forum. Uninstalled GW2 and attempted to reinstall. Now the installer does the same thing as the launcher did (downloads its own update and then closes). Can't even reinstall GW2 now.
