Adobe flash player update with gpo

Hi all,

I would like to deploy flash player version 19.0.0.226 for internet explorer via gpo. we already deployed version 19.0.0.207 succecsfull. Now I added the new msi file to the gpo and set that this package can upgrade the older version. i tried with uninstalling and with updating. both times at my test client the adobe flash player is removed from the installed software list in the system configuration, but when i check the version under flash player, it is the new one. and everytime the client reboots it wants to install the newest version. i also tried to apply the update in a seperate gpo with the same result. flash player is not displayed in th system configuration but in flash player options it shows me the newest version.

what do i wrong?
