The issue here is OTVDM can't run all InstallShield setups because of some missing files in it's system mostly relating to language (in my case) and thus fail. I'd like more details about this if you have some. Some may be arguing that OTVDM will execute these 32-bit executables with a warning …

EDIT: Obviously that's a flaw in MAME's YM2151 emulation, not anything done by Scali or the ScummVM team. Wanted to make that perfectly clear. I don't know how up to date AMAME is but Aaron Giles rewrote all the yamaha fm synths earlier this year. If it's older than that it might be worth trying …

The 80186 has a builtin interrupt controller, dma controller and timer none of which are pc compatible which is why it wasn't used in any* pc clone computers. The tandy 2k requires them for proper emulation. * There's at least one, the Triumph-Adler Alphatronic P50, which has the usual pc devices …

Status: Not working This is misleading, it runs most stuff including Windows 1.0. Dosbox X can emulate the 80186 and a bunch of different kinds of graphics and sound chips.. I don't know about the special version of DOS it ran though. You could probably get it to load it from a floppy as a booter. …

I think FT_Thunk is windows 95/98/me only, it's not available on win32s or nt. Win32s came with the earliest version of comctl32.dll but it might require a newer version.

This is the same crash as if it's run from the cdrom. Turns out it's intentionally dereferencing a null pointer. Try https://ci.appveyor.com/project/otya128/winev … 705sc/artifacts .

Standard mode windows does none of that which is why there can be only one DOS session at a time and why it's always full screen.

Does it display an error or just quit? Anyway, I'll probably need a trace and catching the crash in the debugger again might help.
