How to Handle Non-Zero Exit Codes

When using SMS to deploy software in the form of MSI's, a non-zero exit code is being returned instead of a successful zero code, even though the software is being installed correctly. I've heard this could be a problem with MIF files not being found.

From the microsoft.public.sms.admin newsgroup
What you should do is have your Windows Installer installation create a Status MIF file with the actual success reported. You would need to specify a '/m mifname' on your 'msiexec /i' install line, and have the mifname and properties match what you set on the 'Reporting' tab of the package properties.
