11.2.2 install problem

I downloaded and imported 11.2.2 manually using the zman sui command. It validated successfully. I got an error when I tried to install it. Server is SLES 11.1 64bit. current version of ZCM is 11.2.1. the system update page give me this error:

An error occurred when trying to execute the move file command (${content.0.path};${ZENWORKS_HOME}/zmd/java/lib/systemupdate/ZENUpdater.jar) on the device. Check the system-update.log on the device for details.

system-update.log contains this:

DEBUG;Running Pre-Install Commands;;
DEBUG;Getting content for PRE_INSTALL steps of update;;
DEBUG;Got 5 pre install commands;;
DEBUG;Running command: ${content.0.path};/opt/novell/zenworks/bin/zenupdater;;

ate/ZENUpdater.jar;;
DEBUG;One or more pre install actions failed. The update will not be processed
(Update for ZENworks 11 SP2 (11.2.2));;

I'm not sure how else to figure out what's going on. are there any other logs that might show more details?
