    Windows 8 Pro + Media Center


    Apologies for all the screenshots, but I feel it would be more helpful in 'showing' you what's wrong. I tried that and this error came up:

    Upgrade key activation errosr usually occur when the underlying licensing is not interpreted correctly...

    Try:

    Regedit:

    LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/setup/OOBE/mediabootinstall Change its value to “0″.

    In elevated Command Prompt, type the following: “slmgr.vbs /rearm”.

    Restart the computer

    Type SLUI 3 and activate with your product key again.

    Hope this helps...

    Hi there Superfly, I can't manage to find mediabootinstall in the OOBE directory for some reason

    Open an administrator command prompt: start->cmd->Ctrl+shift+enter
    Paste the following line in:
    Code:
    REG ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\OOBE /v MediaBootInstall /t reg_dword  /f /d 0


    After enter:

    Code:
    slmgr /rearm



    When prompted, restart your computer.

    Enter your upgrade product key

    I don't mind screen shots. That is likely because under normal circumstances you can't go directly to Media Center. Official install media will only let you install 8 or 8 Pro and won't accept a Media Center key. The only way to enter and use the Media Center key is through "add features". It's debatable whether you should or shouldn't have gotten that error but it won't help you sort this out.

    I've used this trick to go back to Windows 7 Home Premium, from Ultimate without having to reinstall. UNAWAVE - Downgrade Ultimate to Home Premium or Professional
    I do believe there are a few members here that used it to go back to 8 Pro from Media Center when their media Center wouldn't activate. I'll have a look for the treads a little latter. Try what Superfly is suggesting and save this for a last consideration. Anybody with 8 Pro installed can look up those registry keys and post a screen shot or tell you what they should be. They are likely case sensitive so a screen shoot would be ideal. My two 8 PC's are media center so that's no good.

    Just curious as to whether you made any headway with your issue?

    Unfortunately not, I've been busy lately and haven't had time to try anything other than the solution that Superfly posted (which didn't work.) I'm considering phoning Microsoft and raging at them.

    OK, I was just wondering if you made any headway. My brother in law has the same issue on his PC. Other than that he didn't say much about it. He's away at the moment visiting his son. I'm not sure what he's done to try and fix the issue or if he fixed it. Work on it when you have time and keep us posted please.
