I recently bought the PC Game "Rush For Berlin". When I try to hit "play" on the startup screen, it brings me to another small, grey screen that says "Deep Silver Protection System", and states : "to launch the application, you need to install additional libraries on your computer. Would you like to install them now?" I click "yes", and then another gray screen comes up as soon as I hit "yes", and states: "error", to install the application you must have administrator privileges on your computer". I own my own laptop, hence I am the administrator and have all administrator privileges. What should I do?
