Needing To Uninstall. Game Not Found.
If it’s not showing up under add/remove programs, then you can just delete the folder. Refunds are only granted if the purchase was made from the original Anet store within the last 30 days. If you purchased it from another source, you will have to discuss your refund with them. If Anet refunds you, your account is closed permanently. If you ever decided to try to come back, you would not be able to repurchase the game to reopen that account. You would have to create a brand new one. It does mean any character names you had would be locked as well.
