Is there anything I need before I get started?

Unfortunately, yes - molscript requires bison to interpret command input and a compiler (with OpenGL support) in order to generate the binaries. Windows (by default) includes neither. Many tend to use cygwin to satisfy these requirements, but I haven't tried it (although it should compile in a straightforward fashion in this case). My preference is to use a minimalist approach that doesn't rely on 3rd party DLLs - thusly, I recommend MinGW to satisfy the compiler/linker necessity, and the GnuWin32 tools to supply bison. In all, you'll need:

How do I install it?

Once installing all the necessities above, unzip the original molscript sources and the povscript+ patches into the same directory. Before actually compiling, make sure all the MinGW/bison commands are in your PATH ("echo %PATH%", or just "set PATH=%PATH%;c:\mingw\bin"). Then fire up a command prompt under windows, and cd to the molscript directory. To compile the binaries, type:
win_pov_setup.bat

make (might be "mingw32-make")
And you should now have a (hopefully) working version of povscript+ for windows! (along with a free C compiler to boot) By default, this version only includes support for OpenGL, postscript and povray output, but if you'd like, its also possible to download the necessary libraries to allow png or jpeg output (which are also available as part of the GnuWin32 packages) - just be sure to edit the Makefile. Finally, I've only tried my install on WindowsXP - so I'm not sure how/if this will work on other Windows releases.
