Game takes 2+ minutes to start since update
If you were using the 32-bit GW2 client before the update, with no issues, you might consider moving back to it.
See the Sticky in the Account Support sub-forum for more information.
Good luck.
I don’t know what client I was using, I never had to choose anything before.
UPDATE: Switching back to the 32 bit client by adding -32 to the launch shortcut fixed it. Thanks.
No problem, glad it worked for you! =)
