    When does this error occur exactly?

    Personally I suggest to open the within Applications/Utilities as it often gives better information about errors.

    • Bill Lamb

      Flash Player Install Manager[1091]: Unable to execute privileged task.

      As an example

      This one is obviously related to installing or updating the Adobe Flash Player

      First I would try to uninstall any previous version using the Flash Player Uninstaller

      In addition I would also do the always recommended Repair Permissions within the Disk Utility (Application/Utilities).

      After that you should not encounter an error installing the latest Flash Player

      I’m still not sure if and how this might be related to the above 100022 error so feel free to report back.
