When a software installation on a managed computer produces an error, the resulting reports typically display a numeric error code. To eliminate the need to look up the error code when you run a report, you can associate an informative description with the error code. Thereafter, the reports display the description instead of the numeric code.
Examples of how you can use the installation error code descriptions are as follows:
A task that runs a Windows Installer installation fails and returns a numeric error code. The error number is not a standard Windows Installer error. Upon investigation, you learn that the error originates from a custom action in the MSI file. You can add that error number and its description so that future reports display the description.
A proprietary type of installation EXE returns its own set of error codes. If you know the meaning of the numeric codes, you can add their descriptions.
Error code descriptions are predefined for Windows Installer installations. Other installation types might also have predefined error code descriptions. If a description is not defined for a particular error code, the numeric code appears on the reports.
Errors that appear to the end user always appear as numeric codes even if you define their descriptions.
