The recommended solution is to upgrade for version 18.
I'd guess you already tried running the installer by choosing Run this program in compatibility mode (by right clicking and choosing properties) and then right clicking again and Run as administrator.
Your next option is to run a virtual PC within your Win7 computer (or a dual boot system) with a compatible OS running on the "other" machine. With Win7 Pro and Ultimate, there is an option to download two programs and install them for a free WinXP virtual computer (XP mode). For the other primary OS's you'll need to have a valid license of the compatible OS to install in program that runs the virtualization or the second boot disc. Then install the Printmaster in the "machine" with the correct OS. You may find you need to save the files to external media to transfer them. (The virtual computer won't let you have one printer installed on both the virtual system and the real computer.)
