well it means you have a game with a windows installer.

(so probably a windows game)

try looking for an install.exe

Strange that a program would try to run Windows though - maybe that's how they did it back then...

There isn't one.

Then it's not a DOS game, is it?

What game are you trying to install?

The game is PYST, it says when I try to install it the system file is not suitable to run MS-DOS and Microsoft Windows applications.

HunterZ, it was common in Win 3.0/3.1 days. Programs that needed windows would simply start it by calling "win <exename>" (from the MZ stub executable, just like win9x programs print some kind of "you need windows" message).

And that actually worked. Win 3.0/3.1 could run a single executable directly that way. I recall being annoyed when programs _didn't_ use such a stub but just said "you need windows". Damn I'm feeling old 😀

So what do I type to make it run the setup?

Pyst is a Windows game (well, I don't know if I'd even call it a game, from what I've read of it). DOSBox is a DOS emulator. You can't run Windows games in DOSBox (yet).

So is there any way to play it on XP?

Maybe try running the installer/setup program in Win95 compatability mode?

And you were saying, HunterZ 😉
