When deploying Adobe Flash Player updates with SCUP 4.5 you might run into a few problems with the installation of the update. My work around to fix that is by creating the update from scratch. In this post I assume that you have a working SCUP 4.5 environment up and running. The update being deployed is install_flash_player_ax.exe version 10.0.32.18 which can be downloaded from http://www.adobe.com/support/flash/downloads.html
