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. Andris
