Problem installing DVD rom that uses Adobe AIR on Macbook Pro

I'm trying to install a DVD-Rom that uses Adobe AIR on my Macbook Pro. First I get a message saying "Installing Adobe AIR command line)" then I get a message saying "The version of Adobe AIR cannot be installed because a more recent version already exists on your system". As soon as I close that message Adobe AIR Application Installer pops up and it seems as if I need to choose another installation package, but I don't know what to do next. Can anyone help me with this?
