What are your CPU cycles set at? Try slowing them down. I usually run into those types of errors when the speed is a tad too high.

I was running at the default which was 3000 cycles. I slowed it down to 10 cycles, and still got the same error.

Thanks

I am trying to install Tempest 2000 (Dos version) from an ISO file

If you are indeed using an "ISO file" then the absence of Tempest 2000's audio tracks may cause problems. You should be using a BIN/CUE image that includes the audio tracks.

Hi,

I have a CCD/CUE/IMG/SUB version and a BIN/CUE version. Maybe I have not mounted them correctly?

I used the commands

IMGMOUNT E D:\T2KISO\TEMPCODE.CUE -T iso -fs iso
or
IMGMOUNT E D:\T2KISO\temp2k.cue -T iso -fs iso

With either, I'm still getting "Divide Error" when I select a language from the install program.

Thanks

Are you mounting a C: drive? I ask because I can reproduce the "Divide error" you describe by not mounting a C: drive.

If you are mounting a C: drive, then perhaps there is some problem with it, such as insufficient access rights to the folder being mounted.

You are the genius 😉

I mounted a different drive letter for DOSbox because I didn't want Windows to complain that I was messing with the boot drive. Now that I have a C: drive it works.

Thank you so much!

That sentence doesn't make any sense. Why would Windows care about your DOSBox C-drive?
Unless you're doing this (you really shouldn't):
mount c c:\

Instead do something like:
mount c c:\dosgames

or maybe even:
mount c x:\dosgames , where x = your data drive letter

You've got it. I didn't do mount c c:\ out of caution, so there was no C: drive. I had performed mount D D:\ , and put my games on D:

Thanks

Just to make sure you've got this you did "mount C D:\" , you do not want to "Mount C C:\".

I did not want dosbox writing to my actual C: boot drive or attempting to do so, so I did not mount my actual C: drive as the C: drive for dosbox 😀

Thanks again
