I would expect with the currently supported PPM-versions mostly if not all only supporting these Office versions, PSO has further developed the generator for these versions. I don't have access to the tool however. Maybe someone else here does.
Huh...yeah the "9.1" version ran fine in 2003 but no longer works now that we've upgraded to Office 2007. It seems to install fine, and the menu items are there, but clicking them give a message about the macro not being available.
