Just tried the latest version and still getting the Error 2753.The File 'InstallAX.exe' is not marked for installation. it's really annoying now even after running clean up tools removing AV. It's like they just cannot seem to design a MSI file properly.
Our solution was to use Wininstall LE and take a snapshot of before and after install, then rebuild a msi package. We have now managed to get it deployed but there is another problem. IE8 is now whining about flash running because of the protection mode. Nothing ever seems to be simple, you would think in this day an age that these companies would actually work with each other.
