The new version of the free installer has now been released, featuring the same UI as the other installers and updated download links to source forge. The app also features a feature list comparing what you get in the free and paid apps.
If you have the free app installed check for updates now!
And if you are reading this and don't have my free or paid ubuntu apps then download and try it!
(might take a few minutes for the new version to show up, but its loaded!)
