For 32-bit compilation, no, no additional download is necessary.  
For 64-bit, you need the Microsoft COFF linker and C runtime.  
The installer will try to automatically configure dmd to use 
those if you have them already.  Have you tried it?

Using Win64 from the zip file will require some manual 
configuration, similar to these somewhat outdated instructions on 
the wiki:

There is also experimental support for 32-bit COFF in the latest 
git HEAD. :)
