Hello,

I downloaded the update from the catalog, but when I click on it to install, it doesn't work. "Only one instance of wusa.exe is allowed to run."
Can someone please help me, thank you very much.

    Hello,

    The message "Only one instance of wusa.exe is allowed to run" is due to the fact that Windows Update is running and is already trying to install updates.
    Disable Windows Update temporarily in order to manually install the update, then re-enable it.

    Please press any key to continue the disinfection...
