What versions of Windows does RubyInstaller currently support?
Currently RubyInstaller explicitly supports Windows XP, Windows Vista, and Windows 7 in both 32 and 64-bit flavors. By “explicit” we mean that we accept bugs discovered on those versions, we perform testing of the installer on those versions, and we use code that supports those versions. This doesn’t mean that RubyInstaller may not work on other Windows flavors, it just means that we’ve had to focus our resources on supporting the more mainstream Windows versions.
