    Yes, that is the problem. You'll need to clean install it again but make sure to choose Home edition. Unfortunately downgrading the edition from Pro to Home isn't possible.

    I'd check the installed edition of windows lines up with the product key edition.

    Agreed with DSPatrick, the product key for win 10 home cannot be used for pro.
    So you need to backup all your data and reinstall your windows as home version.
    Here are some docs about win10 clean install:

    Thanks for your time!
