Fixed in ZAM 7.5 IR 4.
If downloading the Interim Release manually from https://download.novell.com, search for ZENworks 7.5 Asset Managment IR 4. The Interim releases can also be set up within the ZAM Manager for the Task server to check the site on a scheduled basis, and download and apply them automatically. Please refer to the Help Section for details of how to set up automatic downloads if desired.
Each interim release is cumulative. If Interim Release 4 is not available due to a newer interim release being placed on the website, be assured that the code needed is in the later release.
