Create package for Adobe Contribute CS5 with AAMEE

Hello,

I'm trying to create a package for Adobe Contribute CS5 with AAMEE but I get a message saying "this media is not supported by this version of AAMEE".  I have already tried with AAMEE 2.1 and 3.1 and I get the same message on both. I'm running this on windows.

any ideas of what might be going on? is there any other way I can get a MSI extracted of that setup.exe?

thank you in advance.
