I try to start the game and I get 3dfx logo, then the game just crashes, no error message just "Prophecy has stopped running"
Try compatibility modes for Windows 95, 98 and XP (right-click the game's shortcut => Properties =>Compatibility tab)
Update your graphics drivers.
If it doesn't work, make sure your system has everything needed to run the game:
- Install AC3Filter
for audio decoding
- Install DirectX 9 redistributable
- Install an MPEG2 video decoder (e.g. this one http://www.si-gamer.net/gulikoza/bin/mpeg2dec.zip
; extract to your WC5 directory and run register.bat)
If it still crashes, try running the game as Administrator by right-clicking the game's shortcut and select "Run as Admininstrator"
Alternatively you could give the OpenGL Patch
a chance, maybe it's more compatible with your graphics setup.
