Environment
Novell ZENworks 10 Configuration Management with Support Pack 1 - 10.1
Situation
Install MSI action generates error 259:
Error installing Pro11.MSI. MsiExec returned error code: 259.
WindowsActions.MSI_ERR_UNKNOWN
There was an error that occurred during an action for bundle bundleName. Would you like to automatically verify this bundle and attempt the action again?
Resolution
This is fixed in version 10.2 - see KB 7003225 "ZENworks 10 Configuration Management with SP2 (10.2)" which can be found at https://www.novell.com/support
Additional Information
This happens especially for MSI installs that take over a minute to complete as they have a large number of associated files, or are run from Network share etc. The 259 means that the install process is still running, and ZEN bundle manager should not generate an error as no failure has occurred.
