i got an idea go to where the game is installed move it to another place lock it, so when u click on ad and remove program it will say cannot find folder
name the folder anythin u want and run it from there , and i know how to lock the folder, and unlock it when u need it start you game, after lock the file and if he finds the file, if he clicks on it, the file will lead him to the control panel but if u rename it then he wont know what file it is. If you put it in the windows files so when it is locked it will have an icon like acontrol panal and when clicked it will lead him there, he wont know that is your game.
PM me dude i will give u step by step
