Hi!

I have had the same problem. It seems there is a bug in the standard
security policy file or it is not working with a standard windows system
anymore...

If you just remove all the text in the file and write:

// Do what you will
grant {
permission java.security.AllPermission;
};

There should not be a problem. Be aware that this is not safe !!!

But you can start from there and see if it works. I
