For Online Computer Support, Ask a Computer Technician
Hello, please make sure you are typing this in correctly. Even for myself sometimes I get my B and 8 mixed up or just simple things like that. If you still cant get it to go, you will need to call Microsoft and try to get it working otherwise request them to re-generate you a new product key and they would email it to you. Only Microsoft can activate these softwares as we all go through there Servers.
