Under Win 7 64 bit with complications run ...

1. The game just did not want to start
2. Error message "Access Violation 000 000 005" (or something similar)

So then pointing to the cheerful Troubleshooting:

1. compatibility mode no matter how set = same error
2. 256 colors = Nope not going

etc. etc.

If you can execute the game in windowed mode you start it. (-w Option behind the diablo.exe)

But windowed mode is not intentional.

"Googling" After long I came across a "Glide wrapper" and make it work then be 100%!

Just search for "svenswrapper" and follow the instructions! Or simply put a .com behind svenswrapper and you're on the right page.

The game itself gets me 5 star but the point deduction gets it that one anywhere on Blizzards pages something about this well-known problem is!

I probably need to say anything, because it simply is a "cult Game" and prepares fun repeatedly even after tens of years to play itself.
