Repair Install Problem Due To SP1

    It's likely something in one of these registry listings which tells Win7 it is a newer version (with SP1) than the DVD which when slipstreamed isn't showing SP1 in its coding.

    Just as changing the Edition ID and Product Name can trick the installer into doing a Repair/Upgrade Install to another Win7 version, finding and changing the coding here which indicates it is SP1 would likely do the same.

    Sure would be nice if someone figured it out. Got any contacts at Microsoft

    Thanks Shawn and Greg

    If I do a reg query of that key, I get a slightly different result:
    CurrentBuildNumber REG_SZ 7601
    BuildLab REG_SZ 7601.win7sp1_gdr.110408-1631
    BuildLabEx REG_SZ 7601.17592.amd64fre.win7sp1_gdr.110408-1631
    BuildGUID REG_SZ 120eeac6-d1df-4811-80a7-a443334c6c2f
    CSDBuildNumber REG_SZ 1130
    PathName REG_SZ C:\Windows
    CSDVersion REG_SZ Service Pack 1
    along with a lot of other stuff. I wonder where the equivalent is on the DVD?

    Yours shows CSDVersion REG_SZ 6.1

    Someone with a slipstreamed SP1 DVD might try setting a Restore Point then changing that key to 6.1, to see if it agrees with the DVD and allows a Repair Install.

    Thanks to everyone who contributed to this thread.

    The reason I needed I to reinstall is that out of the blue I got an "installing device driver" message, and installation failed. Device Manager showed that no driver was installed for my HP printer, which worked well up to that point.The reason for failure was shown as "the core driver package needed to install the printer driver is missing", or words to that effect.I have no idea how the core driver package got deleted.

    I realised from Brink's earlier message the reason for my attempted repair install failure, namely I used the Windows 7 SP1 Disk Cleanup Tool, and I won't make that mistake again.

    I did a successful clean install, and was able to recover my program files, documents, pictures etc.etc. from a Macrium Reflect Disk image I made immediately prior to the reinstallation.I dragged and dropped selected files and folders from the image, because if I simply restored the image I assume the printer driver problem would have resurfaced.

    Best regards,Roy

    Hello again Roy, good to see you got it sorted.



    Have a look at this tutorial at the link below so you will always have system restore points if ever needed, that may have 'removed' the problematic driver for you; be sure to have a look at Method Two, the one I prefer.

    That's great news Roy. I'm happy to hear that to see you got it sorted, but sorry it took a clean install.
