    Can't upgrade install after running anytime upgrade


    I purchased an upgrade key from Microsoft last year and used it on my Win 7 home premium 64 bit installation and upgraded it to Win 7 pro 64. Lately, my system has gotten squirrelly and I wanted to
    do the "upgrade" (repair) install from my CD. The system will not allow me to do this. It says that
    Windows 7 Pro cannot be upgraded with Windows 7 Home Premium.

    So now I'm stuck unless there's a way to uninstall the pro upgrade and revert back to home premium.
    Is there a registry key I can delete or something so that it will work? I don't want to lose all the neat programs I have installed.

    You are going to have to do a few registry tweaks to fool the Windows Installer in thinking you have the previous version. Once you have done so you can continue doing the upgrade repair process however you must do it while the machine is currently booted. (From the Desktop).


    This link provides a good step by step process which you may want to try.

    Please note that I have not completed these steps so please proceed with caution.

    EDIT: I had to attach the link into a text document since the URL could not be copied.

    Hope This Helps,
    Josh! =]

    There are no easy ways around this.
    Your best option is to use the manufacturer's Recovery system to get back to the initial install, and then re-apply the upgrade.

    NOTE: - back up your data to external media first, as the Recovery system will almost certainly wipe at least the C: drive before reinstalling the OS!

    Did the registry tweaks you mentioned, but now it says the version I am trying to install is older than the one I have. Gotta be some way!!

    That won't work. This is a computer I built myself, so there is no manufacturers recovery system.

    Ah - in that case you have a problem.
    You can try doing a repair install using updated media

    Well, I have a solution. Just ordered Win 8 Pro. That will fix it once and for all.

    NAH


    Dunno what u guys have against W8. I have it on 1 machine and it's great. I upgraded it from W7 and it picked up all of my programs. Everything works and it's faster than W7. I just go to the desktop and everything is there. Love the search feature. MSIE 10 is great too. So now I will have it on both of my
    i7s.
