You're still using *DOS*?!
I'm sorry, but POV-Ray for DOS has been discontinued ages ago -- and

In essence, if you want a DOS version of POV-Ray 3.7, you'll have to
take it upon yourself to...
- Find a C++ compiler that is not only able to generate DOS binaries,
but while doing so meets all the requirements outlined in
`source-doc/compiler.md` (we most likely won't relax those requirements;
to the contrary, expect future versions of POV-Ray to rely on more and
more features of C++11, and maybe even later C++ standards), and is able
to build the boost libraries.
- Set up project files for that compiler (or makefiles, or whatever
meta-information it needs).
- Set up compile-time POV-Ray configuration files for that compiler.
- Develop a dedicated DOS front-end (the Windows console version might
be a starting point, or alternatively the Unix front-end).
- Diagnose, report, suggest solutions to, and follow up on any
peculiarities of the POV-Ray code that turns out to get in your way.
- Provide user support (presuming you distribute that DOS version of
Also, I noticed you enquire someplace else about a 64-bit version of
FreeDOS. Don't expect anything along those lines to /ever/ happen: DOS
has immensely strong ties to the architecture of the original 8086 CPUs,
which even as early as in 80286 CPUs was only one of multiple operating
modes. Since the AMD64 architecture does not provide any means
whatsoever of switching back to, nor emulating, 8086 mode once the CPU
has entered 64-bit mode, a 64-bit application started from DOS would
have no way of invoking any operating system functions at all, and
couldn't even give control back to DOS when terminating.
While it would certainly be possible to concoct something /similar/ to
DOS that runs in 64-bit mode, it wouldn't be able to run genuine DOS
binaries, which would defy the whole purpose of the exercise: You could
just as well implement a brand new operating system based on a much more
modern design. Or simply switch to one of the existing ones, such as Linux.
