Hello,

i bought sins of fathers from GOG installed and played for like 15 min to see if it works and it was working without a problem.
Today i wanted to play again but couldn't because of Dosbox crashes. It crashes all the time when i exit a dialog and sometimes when i go to a location, even it may crashes on startup.
Re-installed and tried every graphic mode, none of these worked.
One thing is, before playing second time i added the game to steam, but seems that it doesn't work because when i click steam shortcut it only opens dosbox not the game. Crashes started after that. But reinstalling should solve the problem if it was related to steam.
Anyway i tried steam once, normally i launch the game with gog shortcut on desktop.

Thanks for help, desires to play this so badly :S.

Steam tends to fail at opening the required dosbox for the gog-games, so I would just not add it to Steam and play the game normally by using the shortcut provided by the goginstaller.

i noticed that. So i reinstalled the game but somhow dosbox is affected it crashes all the time now

Hi, I had sound problems when first running this game and solved them by burning the ziped files to a disc (the gog zipfile is basically a cd mirror) and installing them using a custom installer from zetafleet. Perhaps installing the game this way solves your problem too because the game doesn't use dosbox when installed like this (at least I think it doesn't because DOSbox 0.74 doesn't work on my system for some reason, maybe it uses an older one). I found this in the following thread, post 23 and 25 by Gremmi:

Here's the highlights:

One last thing to try if you're desperate to play the game (though this is a bit of a lengthy process):
Browse to the installed folder
Find the file GK1.gog.
Open this in WinRAR and extract all the files to a directory (say C:\GK1)
Download and run the GK1XP installer from http://gkpatches.vogons.zetafleet.com/
Point the installer to the GK1 directory.
This will then install the Windows version for you, which should avoid any DOSBox sound conflicts.

Ah, I just tried it myself and the GK1XP installer's been updated since last time I used it so it only works off a CD. You'll have to burn the extracted files to a CD, then run the installer.
