    Hey all having some issues. I installed windows 8.1 x64 and used a key from another site to get it installed I was then supposed to use my windows 8 key to activate it but it wont accept it it says : you cant use that key to activate this copy of windows" any ideas? The windows 8 key is for windows 8 pro upgrade. I downloaded the windows 8.1 iso from here cheers

    If the key you used was a genuine one for windows 8 (not a key collected on bad sites) i don't see what is the problem then.

    Definately a legit windows 8 key I bought it direct from microsoft at launch :( It wont let me change the key from the one I used to get it installed to my own key.

    The key you entered during installation may have been a Windows 8 Core key, so you may have ended up installing Core instead of Pro. It will then not accept your legitimate Windows 8 Pro key.

    ok so I am guessing I have to reinstall and find a pro key to get it installed? Then switch to my own number?

    Then launch 8.1 dvd/usb within windows 8 by setup.exe, choose upgrade without internet connection. Once done open a command prompt as admin and type slmgr -ipk followed by your product key, then activate online. ;)

    like Kelorgo said, you entered the core key instead pro during setup. You must reinstall by entering generic pro key and then you can use your own key for activation

    There are different reasons, check which edition you have installed and make sure you use the proper key.
    Type the following command in order to view the error details in the command prompt as admin.

    slui.exe 0x2a 0xC004F069

    Thanks

    When I paste that in cmd I get an error has occured contact microsoft to resolve the problem. In system it does not say Windows 8.1 pro. It just says windows 8.1. If I try running the installer from within windows it says I already have windows 8.1 installed. it says I can add features can I change it to pro that way or do I have to boot off usb and format then reinstall?

    there is no server yet responding to 8.1 because of the new V6 protocol
