It says:

"Dilplay mode 1024x768x8 not found. Cossacks should not run."

After choosing "Retry", I am able to get to the menu, but not able to change the resolution. When I try to start a game then, it completely crashes.

I am on Win 10 Pro.

Please Help! :(

Does your monitor not support such low resolution? Some tellies do not.

It does support low res.

I use a tripple-screen setup, but even deactivating the other 2 monitors it won't work.
