Acrobat is annoying in it's installs.. You need to insure that you have any previous version uninstalled. I ran into a Support Desk ticket a couple of weeks ago where the guy was running Acrobat 5, but when I cleaned it up there was a leftover from version 3.. Anyway, the point being, if you any leftovers from other versions, it will wreak havoc.. Here is a bit of code from ScriptLogic that may help - C1043 - Deploy Adobe Acrobat Reader 5.01
