I tried to follow the instructions on that page, but the program still not runs. I set up the registry the way it was described. I set the dbghelp.dll to native, and I overwite the dbghelp.dll in windows/system32 directory with several versions (5.0, 5.1, 6.6, 6.11). I got a long debug message only if I have ran the application after I have replaced the dll with the 6.6 version. But after that the same 3 lines messages appeared again and again. (I don't understand why the long messages appeared only once, but this is what is happening) The output was: Code: Command:~/wine_a1701demo/drive_c/Program Files/1701 A.D.
