HeartsAndRainbows: From what I've heard about Windows 10 so far crashes like this one will keep happening with various games. There is a high probability this was caused by a Windows 10 update. You could either try and remove updates, switch to another OS (either just for gaming or for everything), contact GOG's support or wait for someone to have that exact same problem (or at least someone who
knows how to fix it) to make a post here after figuring out a solution.
In theory, Jazz Jackrabbit runs on a wide variety of OSes, so if you switch out your OS I would recommend a switch either to Windows 7 or
Debian.
That being said (and while there is always a
chance that someone in the community might able and willing to help you) it's probably the easiest to contact GOG's support about this issue. This
might also lead to patches for future players.
Oh, and whatever path you choose: Best of luck!
Hey, thanks. I have similar issues with a few other games, including most of the Delta Force series, which I bought here because the Steam versions refused to start after a while. Alas, these crash too. I tried various compatibility settings, nothing worked. I also believe it is a Windows issue, because the games used to work before (though I don't know about Jazz, I bought it recently).
