The Min Version property further defines the MSI engine's search for installed versions to upgrade. The previously installed version's upgrade code must first match the value specified in the Upgrade Code property. Once a matching upgrade code match is detected, the search can be narrowed by the minimum and/or maximum version specified and whether the versions are included or excluded (indicated in the Include Min Version and Include Max Version properties).

This property contains the minimum version number of the product that you want your current version to update. The field can be populated in one of the following ways:

- If you added an upgrade entry to the Upgrade Paths tree by browsing for and selecting an .msi file on your system, the version of that .msi file automatically populates the Min Version property.
- You can also type the minimum version in this property field in the format 0.00.0000 or 00.00.0000 (where the zeros represent the version number).

You must specify a value for at least one of the Version properties: Min Version and/or Max Version.
