    Windows Update Error 80070641

    Hey peeps. I already figured this out, but since it gave me a lot of trouble
    i just thought i'd share it with everyone so others don't have to endure this
    annoying thing. This is especially helpful to those of you who, like me, mess
    around with services. Anyway, I was trying to install Windows Updates on
    Vista. It kept saying that all of the updates failed and said that the error
    code was 80070641. It wasn't listed in the help and support window, so that
    wasn't much help. Anyway, the problem with this one is kind of a
    head-slapper. If you get this message it means that your "Windows Installer"
    service is not enabled or not started. To fix this click Start>Control
    Panel>System and Maintenance>Administrative Tools>Services>Give User Account
    Control password or confirmation>Make sure the service called "Remote
    Procedure Call (RPC) is on. If it's not, follow the same steps below that it
    says for windows installer. >Scroll Down until you see "Windows
    Installer">Right click>Properties>Under the General tab, make sure the
    startup type is "Automatic". This will start the service when windows starts
    (you want this if you are going to try to install anything)>Click OK>In the
    left-hand pane of the Services window, where it describes the service, click
    start. You should now be good to go. Try to install the updates again and if
    it doesn't work, you didn't get error code 80070641 or there's something else
    wrong. Hope this helps

    Thanks for posting this. Now, was Vista an upgrade, if so over what, or,
    was it installed you onto a clean Hard Drive, or, was this an OEM
    system ?

    If we can find out just WHY, by whom or by what, the Installer service
    was set to be Disabled on boot, that would be very helpful.

    RE: Windows Update Error 80070641

    I treid following the instructions in the first message, but could not find
    Windows Installer, only Windows Modules Installer - is this the same thing?
    Either way, it would not allow me to save the setting as 'Automatic' when
    going into the Properties, defaulting always to 'Manual' and therefore not

    I've tried so many times to install the following three updates:


    and still, the same error code 80070641 comes up, with no explanation
    anywhere of what it actually means.

    I'm getting really annoyed with this, as these updates are deemed
    'important', but my system is unable to do anything about it!

    Please can somebody help!

    (I'm running Vista Home Premium, 32-bit, if that helps)

    Thanks to one of the other discussion threads found a solution that worked
    for me. I have SpyDoctor installed. Had to disable OnGuard - then install
    worked! (enabled OnGuard afterwards)

    I've the same problems :
    - unable to install/uninstall software coming with Win Installer
    - problems on Win Update
    - error 80070641 when installing *msi.package

    Following your post I have :
    - Service RPC : Automatic and started
    - Service Windows Installer : Automatic but it doesn't want to start ("the service have been started and then stopped, some services start only when is necessary...." this is the message I had!

    I did'nt understand when you speak about "Give User Account
    > Control password or confirmation"????

    In another forum (in German...) I read that we have to modify manually the key :
    HKLM\SOFTWARE\Microsoft\Windows\Current Version\Installer\Secure
    but I didn't understand how? Google translation : The key was without details authorisation and without owner
    How is your "HKLM\SOFTWARE\Microsoft\Windows\Current Version\Installer\Secure" key???
    THX to everybody...!!!!

    SOLVED yesterday :
    - I've downloaded Win CleanUp Utility
    - error on start (no vbscript)
    - rename msicuu2.exe on rar and extract all files
    - a txt file explain that you have to rename msizapU.exe on msizap.exe
    - ok, I have the window with the last WinInstaller softs installed
    - I delete some of them (the recent ones and the unuseful ones hoping to delete the one causing the troubles)
    - start/run : regsvr32 msi.dll

    I try to install Opera 9.24 (pack msi) and WOW it's OK :-)
    After that all the install was OK :iTunes, Opera, Win MobileDevice, WLM, demo Games, WMPpluginFirefox, Skype.....
    So Happy!!! if this can helps....

    Hi ;-)
    >i installed this msicuu2.exe and had no problems...
    >should i have gotten an error?
    not necessarily : I had it but if you have no problem go through following steps...
    - a txt file explain that you have to rename msizapU.exe on msizap.exe
    ---> do you see this text file? have you renamed msizapU.exe on msizap.exe?
    ---> where did you stop the procedure?

    Following steps :
    - ok, I have the window with the last WinInstaller softs installed
    - I delete some of them (the recent ones and the unuseful ones hoping to delete the one causing the troubles)
    - start/run : regsvr32 msi.dll

    Hope it was useful for you!

    Re: Windows Update Error 80070641

    Look for context in the logs. Use both the hex and the decimal representations
    of the code you are getting.

    BTW note that 0x0641 == 1601

    <cmd_output OS="XPsp2">
    F:\>set /a c = 0x641
    F:\>net helpmsg %c%

    The Windows Installer Service could not be accessed. This can occur
    if you are running Windows in safe mode, or if the Windows Installer
    is not correctly installed. Contact your support personnel for assistance.

    Hmm.. I guess you could also search this newsgroup for suggestions which
    involve the "Windows Installer Service" (Use the quotes when you search.)
