Installation Error with Java

When using the Zuly 1.018 Windows Installer file, I'm receiving the following error from the command prompt:
C:\Program FIles <x86>\Java\jre6\bin\Java.exe -jar "Zulu Installer.jar"
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
Any ideas?
Thanks
