When deploying Microsoft Office updates (including service packs) you may run into a seemingly new error (return code). This error may or may not be of concern to you. If you don't want a particular error code to be marked as a failure you can add the code to the Success Codes field in your Installer.
Here are some codes you may want to consider as Successful. (Of course there may be some reasons you still want these to show as Failed... it's your call)
- 17025 = Patch already installed
- 17028 = No product installed for contained patch
- 17034 = Required patch does not apply to the machine
