Hi Brad,
Very weird. The default Java on my Windows 7 64-bit was Java 32-bit. I downloaded and installed Java 64-bit and it now is the default Java engine and it works with my BSPCloningWizard.
You might try adding the path to the javaw into your Environmental variable PATH to see if that help.
Otherwise I can only suggest un-installing both Java and MQX, reboot and re-install to see if it fixes the path issue.
Sorry I cannot reproduce the issue.
Regards,
David
