Simply don't work

I click on the program and there is a command line that briefly shows up before closing. Alright, I figure I then have to run it through CMD itself.

So I type cd:\Users\Me into CMD (which is where I put the executable and the image, and then enter hicolor-v0.3.1-win32.exe hicolor quantize -5 example.png

But then it says "invalid command" and simply tells me:
hicolor (encode|decode|quantize) [options] src [dest]
hicolor info file
hicolor version
hicolor help

I don't know what I'm being asked to do. Even hicolor help produces "invalid command"

Instead of

hicolor-v0.3.1-win32.exe hicolor quantize -5 example.png

type

hicolor-v0.3.1-win32.exe quantize -5 example.png

In the usage instructions hicolor is the name of the program.
