This error typically appears when the Flash player is in use, preventing a new install. You should close all browsers or other applications that may be using Flash (which could be an Instant Messaging application for example), It will be worth looking at the Task Manager and close any Flash Player related processes (they have 'FlashPlayer' or 'FlashUtil' in the name).

    make sure you have the correct processes closed. If flash dependent processes are NOT closed, then flash will not install/update PERIOD. I have tested this with the new offline installer and they MUST be closed.

    Open a CMD prompt Run a Command as Administrator from the Windows 7 / Vista Run box

    :: Kills any (known to me) programs that use flash player

    taskkill.exe /im plugin-container.exe /f

    taskkill.exe /im firefox.exe /f

    taskkill.exe /im iexplore.exe /f

    taskkill.exe /im flash* /f

    taskkill.exe /im Steam* /f

    taskkill.exe /im TWC.Win7.exe /f

    That should close any flash dependent programs (that I know of)
