    win7 install

    Tried to install win7 on a new hdd but MS claims product code invalid, still have the original box that win7 came in. Have been using win10 for the biggest part of the year---what gives,. Is it after using win10 for a while MS no longer recognizes win 7?

    If you activated this Windows 7 previously with this disc, you cannot activate it again.
    You can skip the product key in the install and Windows will install, then try putting the key in again. If that fails, then call Microsoft to activate your Windows again.
