Hello how do you uninstall Planetside 2 and it's launcher because I cannot uninstall the game or it's launcher. I get this message here is a pic: https://imgur.com/a/6zDalsU
you need to uninstall the game directly from the launcher. Click the little wrench, and it should take you to a page where you can uninstall.
How do I remove it from my system ? In the Control Panel I still have it. It also leaves files behind in the installation folder.
once you've uninstalled it using the launchpad there shouldn't be any files left. Even if there are files left, you should be able to safely delete those as you normally would.
