    unknown installation running


    I can't install or uninstall anything. I get a message saying another installation is running, but I can't locate and don't know of any.

    Hello gmcatee, and welcome to Ten Forums.

    You should be able to restart the computer to clear this, and then be able to install and uninstall.

    Check in Task Manager in the Processes tab to see what is running to see if it may help narrow down what it may be from.

    may be inexperience but I have not been able to identify anything odd in processes, and there have been no annotated recent downloads

    Scan your PC with you anti-virus and anti-spyware, run Disk Cleanup utility to clean up temp files.

    This was my problem, too.
    Right click empty space on taskbar. Click on Task Manager. Choose Processes tab on the pop-up screen, if not already showing.
    Scroll up or down until you see "Windows Installer" in the processes pane. Click once on it to highlight it. Click on "End Task", at the bottom right corner. A small popup will show warning you about stopping the install. Do it anyway. Done.

    One more thing to try: Windows Repair (All in One), one of the click boxes addresses the Windows Installer.
