If I install a new piece of hardware (such as a new video card, RAM, hard drive or a new motherboard) into my computer, will I have to reactivate my game?
No, there is no need to reactivate unless you change several pieces of hardware at the same time. Before you change several pieces of hardware at the same time, please make sure the serial is revoked correctly. Following this process, you will be able to upgrade your computer as many times as you want. However, should you encounter a trouble launching the game after installing some pieces of hardware, you can download a revoke application here. In case this process does not work, please contact Ubisoft Customer Support (‘Ask a Question’ tab above) for instructions.
