When I try to open or run .JNLP Files I always get a Unable to launch application error, I have JRE(Java Runtime Enviroment) 6 Update 6. I have tried many JRE Versions including JRE 6 10 Beta and still the same error pops up.
Heres what I get when it happens:

There was another Java application I tried, It was some kind of old Java web start Application. When I tried to open the JNLP file with that it happen to start downloading the JAR Files through it as it should but when it is near completion it pops up that it cannot run it and that it's apparently corrupted. I tried at least 7 times got the same thing. I've searched all over and can't find a solution to this problem and it is indeed annoying. I hope someone here can help me out.
Here is what I get when it says the file is corrupted:
An error occurred while launching/running the application.
