    Repair Windows Installer Service in Vista (All Versions)

    For all those unfortunate souls searching and Googling for how to repair the
    Windows Installer Service, I have some info for you. A couple days ago I
    tried to uninstall one of my apps and stalled on an error "Windows Installer
    Service cannot be accessed". After many trials and errors trying to fix this
    issue, I stumbled upon a new fix for this issue that has worked in all these
    situations where the Windows Installer Service will not manually start and in
    essense, not allow install or uninstall tasks to complete.

    Here's the easy steps:
    1. Go to a Windows Vista (Any Version) computer that has the Windows
    Installer service running correctly and run regedit(Start-Run-Regedit)
    2. Go to the location
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msiserver
    3. Right click on this key and select "Export" and save the key to a Flash
    Drive or other.
    4. Run sfc /scannow on the damaged Vista computer - you won't need the
    install disk as it goes to backup files on your HD. Do not reboot when
    complete
    5. Double click saved .reg file from working machine and import registry
    settings into damaged Vista computer.
    6. Now reboot and try to install/uninstall

    If many of you have success with this method, please post this fix around
    the WWW as I went through over 1000 links with users having the same problem
    and not being able to solve it. Shame on Microsoft, very sloppy. It would
    have been so nice if Microsoft released Windows Installer 4.0 as a standalone
    installation with Vista's release so I could have repaired it, most users
    have been doing fresh installs to fix this. Get your act together
    Microsoft!!!!

    "The CAT" suggestions worked for me. Thanks for sharing "The
    CAT" .....just to add (more like subtract to be exact) one need only
    run the exported reg key on the damaged machine to "fix" the
    issue...no need to restart nor to run the sfc /scannow.


    If you cant get your own reg key from a friend running vista, then you
    could try and use the "clean reg key I used" download here:

    Note the file is about very small (about 6.7 kb), I named it :123.reg

    Take care.

    this worked great. however i do not know if this is the case for everyone, but just encase here goes. i started with checking the windows installer service and trying to start it and set it back to automatic. no luck. went to google to find solution, found your post. followed your instructions. tried to install o@o defrag again same message. went back into services to see with your fix if i could start the service this time, and set it back to automatic, worked. so in a nutshell you might want to let people know the extra steps if needed after your fix. thanks for the help. just got done reinstallking vista and almost all of my programs and settings. was not wanting to have to start from stratch. thanks again.

    I tried this solution with your "clean reg key" and the problem was not fixed. Services shows installer is started and that it is set to automatic. However, if i try to uninstall Adobe Reader for example I get that message that the windows installer cannot be accessed. Will I have to reinstall Vista Home Premium 32bit to fix this? I can install and remove other programs I presume because they don't use the Windows Installer.

    then please default to cats original post.

    1. Go to a Windows Vista(any version) computer that has the Windows Installer service running correctly and run regedit(start-run-regedit).
    2. Go to the location
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msiserver
    3. Right click on this key and select "Export" and save the key to a Flash Drive or other.
    4. Double click saved .reg file from working machine and import registry settings into damaged Vista computer.
    6. You may need to go back into services after the import and start the Windows Installer service and set it to automatic.
    7. You may need to restart the machine and then try an install or uninstall and check that the service did start and that it is set to automatic.

    i did not try the .reg key download.
    i got my copy of the key from my roommates computer.

    This solution didn't work for me. I did all the steps and replaced
    the
    registry key, but nothing happened, i kept getting the same error.

    I have the problem kinda pinpointed though: at least in my case, it's
    caused by one of the windows updates - i haven't figured out which
    one
    yet though. My next step will be install the updates one by one to
    figure out which one is messing the whole thing up, but that takes a
    lot of time


    The weird thing is, with so many people complaining about it, howcome
    haven't they issued a report about it yet... I'm seriously thinkin
    bout going back to XP
