In file motiro/README.en there is the following text:

GET IT RUNNING=====

Motiro is developed and tested more often on some flavours of Linux -- speciallyDebian, Ubuntu, Fedora and Gentoo. These probably should be the best availablesystems to host Motiro, but it has been tested and seems to work pretty well ontop of Microsoft Windows or Mac OS X....

In which version of Windows does it work? In which version was it tested?
