Acrobat 7 is not compatible with anything beyond Windows XP. Beginning with Windows Vista and forward, there were changes in the way drivers work such that the Adobe PDF PostScript print driver instance needed to be modified. The first version of Acrobat that was fully compatible with Windows Vista, Windows 7, and Windows 8.x is Acrobat 8.1. If a user installed Acrobat 8 on such a system and then applied the 8.1 update, the Adobe PDF PostScript printer driver instance appears and works.
Alas, Acrobat 8 is no longer licensed by Adobe. Your upgrade path now is to Acrobat DC Pro.
