Looks very similar to NTVDM crashes in Windows 10 32 bit when executing nested

32 bit DPMI programs:

- any attempt to run DJGPP program directly or indirectly (for example through bat file) fails

Microsoft broke NTVDM DPMI support some years ago in Windows 10.

I have not tested Windows 7 or 8 but according to some tests

(http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp/2020/04/15/16:34:15):

- worked in Windows 7 32 bit some time ago

- did not work in Windows 8 32 bit that time

Also: have You set DPMI memory limit to something larger than the default 32 MB? There is no need to

to reboot after adding setting to registry for that.
