I think you wrote the command line yourself?
Please be advice that some Msi fonction don't work with landesk packages. You only should use the features present in this windows, or if you need more create a a batch packages to launch your special msi command line .
Command line looks wrong you need /X productcode. Run msiexec /? for help. Also to troubleshoot run the command line outside of LANDesk first to make sure it works.
