My operative system is Windows 7 Ultimate x64. I'm thinking, that this game could by x16 or x32,so I need to buy new game or I need a patch, or this is not bit problem?
The game would be 32-bit. It's way too new to be 16-bit (published in 2005). Most 32-bit games work fine with Windows 7 x64 though there are a few exceptions.
In
***Draclvr's Windows 7 thread*** there is an entry for the game:
Delaware St. John games. Judith played all three. The only game that had a problem was the second Delaware St. John. If she didn't reboot the computer each time before she played, all she got was a black screen. I don't know if playing in XP compatibility mode was tried.
So you can try those suggestions:
Reboot before playing
and if that doesn't work...
Try using compatibility mode for XP (right-click the game shortcut --> Choose Properties --> Compatiblity tab --> Choose XP and save the changes)
