Reading from your other post...when you install Acrobat 8 Pro, it will tell you that only one version should be installed on one machine. Therefore, it should have "killed" the older versions. The version 8 installation should have installed version 8 of Distiller. If there is NO version of Distiller on your computer, then try installing Acrobat again. I have Acrobat 8 Pro AND Frame 7 installed, and Frame works fine.
To know that everything is OK, when you print from Frame, select Adobe PDF as the printer. It will make the PDF directly, doing the distilling in the background; no need to use Distiller directly, unless you want to. If there is NO Adobe PDF printer, then something is wrong with the installation process.
