It worked for me today with MiKTeX, because I kept the previous installer in a place where I could identify it with what I installed. That's not as user friendly as NEWS, but it doesn't ask Duncan and anyone else who works on Rtools to rearrange their priorities to document something that I rarely read. (Even if I RTFM 24/7, I can't read fast enough to keep up with the changes and additions to TFM.)
