Guild Wars 2

1. For the first step go to your start button and on the search box type cmd and hit enter (you should run cmd.exe). Then you get this DOS like box. This is where you type ipconfig -flushdns (hit enter) and then type ipconfig -registerdns (hit enter and wait about 10 seconds).

2. After this, and this step is what really did it for me, change your DNS settings. To do that, go to your network connections panel (you can access it by going to start»control panel»network and sharing center»change adapter settings (the option on the left). And then right click on your local connection icon and hit properties. Then you get this list of items, click on the one that says internet protocol version 4 and hit the properties button.

3. Finally this is where you change your DNS settings. You don’t need to change the IP adresses. So on the first fields type 8.8.8.8 and on the second field (alternate) type 8.8.4.4. Hit ok, close all these windows, wait about 20 seconds (sometimes more it depends on the internet conection) to settle up. And try to execute the launcher. If it runs smoothly then it has been fixed!
