2015/12/19 update: Google code is now read-only, if the download link fails please go to Github to get it.
Note: I won't put any future new version's link here, please find the link in each version's page (tag: release). There will be a download link in the end of each article.
If you have problem getting files please write me a comment here.
Note: I will not send any copy of RU through email because I am really lazy. Please don't ask me to send you RU.EXE.
