Adobe Flash Player 32.0.0.223 keeps asking to update

Hi, I package software for my college. Here is the command line I use for the installer:

wmic product where "name like 'Adobe Flash Player%% NPAPI'" call uninstall

msiexec /i "install_flash_player_32_plugin.msi" /quiet /qn /norestart AutoUpdateDisable=1

This has worked for previous versions of Flash Player with no problems. But my supervisor has told me that he's been getting reports of people saying Flash Player is asking people to update it but I've never experienced this myself. We want to prevent this from happening as we use Altiris to deploy software.
