I think the Splatterhouse table was written for Visual Pinball version 8.1, so unless the table name or included instructions indicate that it is for VP ver. 9+, I would use that.
As for Vista or Windows 7, Right-Click on the Visual Pinball.exe, usually VPinball8.1.exe or (for ver. 912) VPinball912.exe and choose Run as Administrator.
And if you are "Mr. B", man do I have a theme song for you!
It's my pleasure. :)
