Glenn,
It will test you.
The *.msi installer for Flash or Shockwave enterprise use should be free of third party junk like Google toolbar. What happened was they delayed getting the *.msi out after a published vulnerability and after the *.exe with Google bundled had been out already for a week which was too long to hold the *.msi back IMO. I can't understand why Adobe would ignore enterprise customers.
Make sure the versions you got when you applied for your "license" are the versions you want (hopefully the latest version so they are minimally supposedly least vulnerable but that won't last). The procedure they have is a pain.
If you can keep back leveled versions of these "pests" off of your enterprise you are ahead of the game. Still its good to look for and remove (as in search and destroy) any but the current versions you want to support in your production environment. If you can get the previous version(s) out and the new version you want in all in one step, good for you. Its a big YMMV. I find making sure there are not current browser sessions open is essential and sometimes a reboot is required to make sure of a clean sweep. Sometimes the *.ocx files associated with Flash versions get locked so even the uninstaller could not remove them. Don't know if its a browser config or what. Deleting won't work for the locked files but renaming then deleting the renamed files on next reboot seems to work. This behavior is not 100% of the time and I have not the time to research it. I guess what I am telling you is don't just assume that all traces of prior versions are gone if you pedantically remove the previous version and install the latest. Check then check it again! As usual it pays to be thorough and is what leads to grey hair, EtOH consumption, etc.
