Right, so, I'm probably missing something very basic, but I'm unable to launch the installer jar. I've set my opening program to Java SE Binary, by setting it to java.exe or javaw.exe in the program files and the ones in the windows/sys32 directory. Each one just causes a cmd window to pop up for less than a second and then closes without further action. I'm using Win8 and 64bit Java... anyone know what's up?
