Diablo was released in '96 and I assume it is DOS based. If so it would need to be run through DOS BOX.
This would apply to any Windows from Vista on .
- D-Fend is a user interface for DOS BOX. DOX BOX is included in the download.
- If the game is DirectX based you may be able to find a fix on a Diablo fan site. This is the case with Diablo ll,
which requires some fixes to run properly from Win7 (maybe Vista ? ) on.
- Good old Games is the best source for easy to install DOS games, but unfortunately they don't have Diablo.
