    I am trying to install a Itunes. I have a bad installation .....

    When I try to install it I get "The System administrator has set policies to
    prevent this installation"

    Then I go to uninstall Quick time and I get " The system admin........."
    same message.

    So I can install it, I can't take it off! where do I clear this restriction?
    I am the administrator!

    Most of us are used to installing an application update over an existing
    version of the program. However, for many programs in Vista, the old program
    must be completely uninstalled before the update or new program can be
    successfully installed. Download and installation of programs or updates
    sometimes fails, leaving broken install debris. Normal uninstall processes
    on Vista are generally inadequate, often leaving program remnant files and
    orphaned registry entries on your system. Buildup of this install/uninstall
    debris can block normal program installation, impair proper program
    functioning, generate any number of error messages, and degrade Vista

    Complete removal of broken installs and incomplete uninstalls is essential
    for normal install processes to occur. You can do this retroactively, after
    debris buildup has accumulated to the point of major computer malfunction,
    using a good registry scanner/cleaner. It is preferred to do this
    proactively, cleaning file remnants and registry entries after each
    uninstall, preventing debris buildup. Proactively, you can remove this
    install/uninstall debris manually with help from Windows Install CleanUp
    Utility or you can use Smarty Uninstaller.

    The best way to remove all the remnants of a partially uninstalled program
    or a broken install is to use Smarty Uninstaller. This program will scan
    your system and list all the programs on your computer, including "broken"
    parts of programs. It will then run the program's uninstaller (if present),
    and then rescan to list any pieces left on your system. Clicking Cleanup
    will then remove all traces of your program and installation of the new or
    update program can then proceed normally.

    A link to Smarty Uninstaller and other information about install/uninstall
    problems can be found at the following tutorial. For information on removing
    an empty listing from your Programs and Features, see the second tutorial.
    The third and fourth links are to good registry scanner/cleaner programs. If
    the preceding doesn’t solve your problem, see the fifth link about your
    Repair Vista Options.

    You may also have a Vista security issue and may need to take Ownership of
    and grant yourself Full Control Permissions of involved folders and files.
