    Cannot Create USB Install Due to 8.1 Product Key


    I already have a Win8 Pro USB installer setup but I don't think it can be used to do a repair install for my Win8.1 Pro upgrade. So I'm trying to create a new USB installer setup specifically for Win 8.1 Pro. However, the Win8.1 setup window is not accepting the 8.1 Product Key that I extracted from Belarc, ProduKey and WPkey. Is there a way to get around that issue so that I can create the Win 8.1 USB installer? Thanks.

    Hello Mel, and welcome to Eight Forums.

    If you like, you should be able to use this below to enter a generic key to install with, then change the key to your 8 key to activate with when finished installing.

    Activate retail Windows 8.1 with Windows 8 Product key.

    Hope this helps,
    Shawn

    Thanks so much Brink, I found a key that worked. Now I can continue with the installer. I really appreciate your prompt reply.
