If you've got cygwin, you can use zeroconf: curl get.pharo.org/80+vm | bash or download directly: http://files.pharo.org/image/80/latest-32.zip http://files.pharo.org/vm/pharo-spur32/win/latest.zip (I think) HTH, Alistair

I am getting network errors trying to download latest Pharo Launcher, so I created a fresh Pharo 7.0.1 and Spotter works fine out of the box.
