Hi,
i have installed Java 1.7, why i need 1.6 too 
With 1.7 runs well too. I cant get over this in installation. Ill suggest too add “install anyway button”
Java 1.6
I dont know about this, I havent changed the installer, nor has Jaikoz been tested with Java 7 yet (because only now is Java 7 becoming availables for Macs).
I’ll look into it for next release, but in meantime sounds like you’ll have to have Java 6 available for installation , but can then install Java 7 to actually run Jaikoz if you wish.
Please give a note, when the installaton of Jaikoz works with Java 7
