Try running with a lower number of cycles - that error usually means that a program is running too fast and tries to do some speed-related calculation that causes it to divide by zero and crash.

well...i tried decreasing the cycles...i still got the same error. i went down all the way to 4 cycles and it stopped saying the error but nothing happened. it went back to the prompt without any errors or opening the programming.

any other advise? the program was origionally used on windows 3.1 computer if that helps.

What program is it? And is it available somewhere?

its an old program. its a lottery program that i can't find out who made it. it's called Astrology or something like that. the file name is ast.exe . i've looked everywhere on the internet. the disks are copies. i put them onto the hard disk and im trying to get them to work that way. the program worked in windows 3.1

Hard to say what's wrong then, as division by zero can be the result
of just anything.

Some stuff to try:
use the latest CVS version of dosbox (see the dev forum)
try some older dosbox versions
use the program from different paths (path length/depth)
use loadfix (with different values)
try to configure the program (some setup or by fiddling out
command line parameters of the program)
try the dynamic core

Some more advanced things:
use win3.x inside dosbox and run the program there (?)
set up msdos using the diskimage support
