Good day

I'd wish to inquire on how to remove your game client from a personal computer system. I have not yet found any uninstallation information provided with your software.

If you're on windows just type "add or remove programs" into the search bar and hit enter.  Then scroll down to the "plarium play" line, click it, and click uninstall. 

If you're on mac or linux just google how to uninstall programs on that system.
