Summary

This article discusses the basic approach to troubleshooting a situation where two or more Add/Remove Programs entries exist after a Major Upgrade installation runs.

Synopsis

Discussion

1. Generate a logfile of the Major Upgrade process: Logging an MSI Installation
2. In the 'Advanced' properties of the Major Upgrade item, locate the 'Detect Property'.
3. Locate the 'FindRelatedProducts' action in the logfile.
4. If the Major Upgrade item is correctly detecting the Major Upgrade item, the Detect Property will be shown being set. If the property is not being set, continue to step 4.
   • Search for the 'RemoveExistingProducts' action to determine if this is running. If there is an invalid condition on this, "Skipping action: FindRelatedProducts (condition is false)" could be seen.
   • Verify that the Detect Property is listed in the 'SecureCustomProperties' value in the Property Manager.
5. In the properties of the Major Upgrade item, verify the following:
   • That the UpgradeCode matches that of the setup you are targeting.
   • That the version number of the previous setup falls between the 'Minimum Version' and 'Maximum Version'.
   • If the version number matches either the Minimum or Maximum version, make sure to set the 'Include Minimum' and 'Include Maximum' properties, to avoid this product being ignored.
   • Unless there are specific requirements to leave certain features behind, or to target specific languages, make sure the 'Language' and 'Only Remove Specified Features' fields are blank.
   • Lastly, verify that the 'Detect Only' property is set to 'No'.

Additional Information

For more advanced troubleshooting, it is possible to blank out the 'Minimum Version' and 'Maximum Version' fields to unconditionally detect any version of the product with the specified upgrade code. This is the most definitive way to isolate a version-specific issue in a Major upgrade.
