acropro.itw in Upgrade folder?

I am trying to use the InstallShield Tuner 6.0 to create a transform for Adobe Acrobat Professional 6.0. I am not seeing an itw file in the install directory. I am using a Upgrade version of the software. I've read in another post that it should be in the 'Adobe Acrobat 6.0 Professional Upgrade" folder, but do not see it. Can someone confirm that I need to have a Full version of the application to use the Tuner? Thanks!
