2005, they might've changed it recently.
the copy I have is a retail version from before they officially released it, as I was doing the Technical Support for the product during Early Adopter up to June 2006.
If it has "Vista" compatible then your copies must be 2007, because Vista wasn't even released in beta for developers until fairly late 2006 (just after I gave up tech support)
The product does work on Vista just as well as it does on XP/2000.
Just for note sake, I also run Vista Ultimate 32-bit.
I would strongly suggest making sure all drivers, and updates are installed for Vista. As I had no end of trouble with older GeForce 5200 cards throwing up that error with the Vista Reference and NVIDIA 96 Forceware drivers.
Probably something to do with how DBP supports resource loading, as it was only an issue with DBP/FPSCreator things, however the lastest drivers for GF6/7/8 this problem seems to have disappeared.
