Could you please try install DW again, and post some info here:
1) The filename of game exec is 'ds9dw.exe' or 'dw.exe'?
2) The filesize and last modified date (should be sometime in 2001) of above file?
3) Can you run English EU patch 1.03 to 1.04? If not, Which file did it have error and stop patching?
Thanks for your feedback. It's rare to meet someone have English EU version so I need more info on it. There are just too many variant versions of this game (which is also a problem for troubleshooting).
