Mobygames tells me, that there are DOS versions of both games available, so they must run (& install) from within DOSBox. Don't run the Setup.exe application, this has been created to install for Windows. Instead of, try to run Install.exe, if available, this one will install for DOS.

Thanks, I got it running now, much appreciated!

Edit:

I start install.exe in DOSBox, and when I select
"Accept these choices and save configuration"
it says "Error creating configuration file"

Have you mounted a drive/directory as the C: drive within DOSBox at a location which your user is able to write files?
