The launcher is a helper application to handle installing and running ElVis. Think of it as a powerful desktop shortcut:
1. Check Java version on your computer.
2. Download & install Elfresco.
3. Check for new versions of Elfresco.
4. Run with more memory.
Download it here for Mac and Linux!
... or, if you're using Internet Explorer on Windows, download the launcher in a zip file
Then extract fwrLauncher.jar from the zip file and double click on it to run it.
