I redownloaded all 3 games after patch 3.3, so they're the latest version on gog. They install without any error. But when I try to launch them (either through short cut, or directly from .exe file, a little error window appears with thiis error:
"Init failed
Init failed, could not load the game.
There is no game file or the game file is corrupted. For more info view messages.log"
Deponia 3 has the option to check file integrity prior to install and it gave no error.
I searched for messages.log and could not find it.
So, all 3 games are notplayable at the moment. Any help will be appreciated.

GOG Support team has solved the problem. For those WHO experience my problem, I post their reply here.

"Unfortunately your graphics device driver is a legacy driver and it doesn't fully support OpenGL 2.0. Mobile Intel(R) 4 Series Express Chipset isn't supported by Intel anymore, and that's why you don't have proper drivers for Windows 10.

Maybe you have access to a different PC that meets the system requirements and that you could use to play the game?"

I installed the game on a newer PC and it worked.

So your own post is the solution for this one? :P
Congratulations on getting the problem resolved.
