Hello. I'm using windows 10 and I'm about to install CnC RA3 Uprising, but then when I enter the correct serial key, when it's about to install, something popped-up and says "Installation can not continue, CDKEY not found". I entered a lot of key given by the key generator, still it can't proceed to installation. can someone pls help? I love playing classic games, it brings me back to my childhood memories.
