Trouble installing on Windows XP machine

Hi there

I seem to be having some trouble installing Zimbra desktop on my windows XP SP3 PC. Shortly after install program starts the following error appears:

java.lang.ExceptionInInitializerError

Error log attached

Try running the installer from c:\ and install to c:\zimbra

Moved install file to C drive
Deleted install directory C:\zimbra
Installed to C:\zimbra
Same error

Sorry
