Guild Wars 2

… can’t be opened.

The title is the message I get when clicking on the GW2 icon, followed by the code: -1712. Cannot open the launcher.
This is annoying because I could before work this morning (opened up and played a bit of the patch). Was hoping to enjoy more once I got home.

If anything goes wrong, ever, do this:

you can try to delete the contents of the gw2 data folder, it’s a pain to get to the right one: this step is a general fix for many tp and graphics issues, even without the previous steps however, it will lose all saved log in/password and in-game settings.
To access this:
1 Click on the “Finder” icon located in your dock or the desktop of your computer to make “Finder” the active program in the finder menu bar.
2 Hold down the “Option” key on your keyboard while clicking “Go” in the finder menu bar. A drop-down will appear.
3 While still holding down the “Option” key, click on “Library” in the “Go” drop-down.
4 Once in the Library folder click on Application Support > Guild Wars 2
5 Move the entire Guild Wars 2 folder to the trash and then empty the trash.
The next time you launch Guild Wars 2 it will recreate the recently deleted folder.

Follow those instructions TO THE LETTER. If that doesn’t work then come back and say so because you have a genuine problem which needs to be figured out

Simply logging out (Shift-Cmd-Q) and relogging often solves this for me.
