The Mercury compiler wasn't written in a way that supports natively running in windows, however I haven't had much trouble running it in a cygwin environment. If you're willing to learn a little UNIX style command like (not that much different from DOS) you can try installing cygwin and then following the instructions in the README.Cygwin and INSTALL files.

Or use Windows Subsystem for Linux and use that environment to try Mercury and lots of other things.
