    This isn't a problem.
    It's a design to prevent unauthorized users to perform certain tasks.
    Installation and uninstallation are some of these tasks that require administrator rights.

    If you are not an administrator, or you do not have an administrator password, you can not install or uninstall.
    Not another way around it.

    I've done an update for a long time on an old computer unused spare XP and Windows Update said that he had to update a large number of files, so I have left to download and install.  Once the 45 updates completed, I rebooted as instructed and proceeded to clean a lot of old data.  Apparently I deleted (7) files for Office M/S that must be installed, because the Winows Update icon in the status bar telling me I had 7 sto update to install.

    Now Win Update always tells me that the files should be updated and starts the process, telling me that they are already downloaded, but it fails every time because they are not where they should be, as I deleted them without meaning to.  How can I do the update for these startup files, or where can I get the appropriate files to allow the update work properly?

  • When I try to download sp1a for windows xp to update I get error message cannot conect to the server. What can I do

    I have windows xp. She badly needs updating. What is the most simple and quick way to update?

    Hi Lynmiller,

    ·         You install the service pack through Windows Update?

    If so, you can try to install the update manually and check if it helps. In addition, it is important that you install SP3 because this update contains several other important updates and security updates.

    Step 1: To install SP3, you must first have Windows XP Service Pack 1a (SP1a) or Service Pack 2 (SP2) installed.

    Download details: Windows XP Service Pack 1a Express installation

    http://www.Microsoft.com/download/en/details.aspx?displaylang=en&ID=19751

  • When I perform a windows update I get error code 80070643 _

    I am running windows 7 home Premium (64-bit).

    I have MS Office 2010 installed as well.

    My problem is the following:

    Whenever I'm doing an update of windows, all updates will install successfully but one. Its an update with the title "update of security for Microsoft PowerPoint 2007 (KB 957789).» And the code error 80070643.

    This update still fails to install. And is flaged as an important update. Also, I don't understand why it appears in the list of updates because I don't have MS Office 2007 is installed. The MS Office installed on my laptop is MS office professional 2010. And I never installed another version of MS office on my laptop except MS office 2010.

    I also noticed that whenever I stop my PC the same message appears saying: "1 update is installed, do not unplug your pc.  I don't know if it's related to the problem or not.

    Help, please.
    Thank you

    I solved the problem.

    No more update "Security Update for Microsoft PowerPoint 2007 (KB 957789)" appears when I do a windows update and no more the messege "installation update 1 of 1 in the process... etc" appears when I stop my machine.

    That's what I did:

    1 not installed MS Office 2010

    2. run windows update and everything was nice and smooth. And the update "Security Update for Microsoft PowerPoint 2007 (KB 957789)" does not appear in the update list.

    3 - I stop my machine.

    4. restart the machine and re-installed MS Office 2010.

    Everything is nice and smooth and no error appears when you perform an update.

    Can someone explain what the problem was?
