If you are having crashes and the like your best bet is to contact Support. They will guide you through some troubleshoot to help you to know what is wrong.

Or you could simply repair the game. Instructions about how to do that can be found at https://help.guildwars2.com/hc/en-us/articles/201863008-Repairing-the-Game-Client.

Or uninstall using the -32 command line argument. (Uninstall doesn’t work on the 64-bit client exe.)

Good luck.

Why don’t you just uninstall at the Programs and Features of Windows.Works every time.

Or, even easier, just delete the GW2 folder and files. Voila! Uninstalled!
