<div id="yiv608532506"><div>Alice 2.x actually does not need Java installed as it comes with its own VM.<br><br>One thing I discovered with this latest version is that if you are using a shortcut or a Dock icon that was created with an earlier version, the latest version, 2.3.1, will not work, and that I had to recreate the shortcut / dock icon.<br><br>If changing the shortcut does not work for you, would you do me a favor and download an earlier version of Alice, to see if it will install and run.
