Just to help out anyone who has issues,
I'm running the following version of windows: Windows 10.0.18362
With the following hardware:
Intel Xeon E5-1650 3.5ghz
64GB RAM
Nvidia GeForce GTX 980
I managed to get the game working after some troubleshooting.
The link mentioned by Schuutje does indeed fix the game but there can still be issues.
Schuutje: Maybe this site will help you out?

I found that trying to run the game with a native display resolution above 1920*1080 made the game flicker and fails to start.
In the fix mentioned "github.com/elishacloud/dxwrapper/wiki/Gangsters-Organized-Crime", there is a thread linking to another post in the gangster forums.
https://www.gog.com/forum/gangsters_organized_crime/broken_on_windows_10_as_well/post25 I didnt have to do this Nvidia fix to make the game work on my machine, so do try without first.
TL:DR
Ensure resolution is equal or below 1920*1080
Install the fix and follow the steps. ( github.com/elishacloud/dxwrapper/wiki/Gangsters-Organized-Crime )
Run the game, if fails try Nvidia fix also.
Hope this helps!
I will come by to extort for money later ;)
