The Linux installer is not working

I downloaded IDEA b666 and tried to run the installer but got the following error:
(Window.java:267) at java.awt.Frame.(Frame.java:398) at java.awt.Frame.(Frame.java:363) at com.zerog.ia.installer.Main.b(Unknown Source) at com.zerog.ia.installer.Main.main(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at com.zerog.lax.LAX.launch(Unknown Source) at com.zerog.lax.LAX.main(Unknown Source) GUI- ]]>
Can anyone tell me what's going on and how I can fix this?

Kind regards, Stefan.
