I have just installed the Zimbra Network Edition 5.0.10 for trial purposes on a new Red Hat box. All is well except that I cannot install the iSync connector on my macbook. I have downloaded the connector from the Admin page (isync-5.0.10_GA_2604.MACOSX_UB.dmg) but part way into the install it fails with the message:

The following install step failed: run preflight script for Zimbra Collaboration Suite - Connector for Apple iSync. Contact the software manufacturer for assistance.

I can only find one or two references to this about the place but they don't match my circumstances.

Any help much appreciated... trial is pretty much dead in the water if I can't get this going.
