I got this:
I am getting a “Technic Launcher has Stopped Working Error”!
If your launcher is encountering this error, a solution is to download the .jar file from http://www.technicpack.net/download/ (pick the third from the left (Linux/Jar)). If you are using Internet Explorer you will also need to change the file extension (the ending of the file) to .jar instead of .zip. Once you’ve done that, all you need to do is double-click on the file to run the launcher.
While that might work, it will also likely either associate all zip files with Java (that is bad) or you would be forced to do that every time (also bad)
