Summary properties for installation packages, transforms, and patches are described in the following tables. Note that the meaning of a particular summary property can be different depending on whether the database belongs to an installation package, transform, or patch package. For more information about the property IDs, PIDs, and types, see Summary Information Stream Property Set.

Installation Packages

Summary property Meaning of this property in an Installation database

This property should be set to Null in a final shipping database. The installer sets this property to the value of the LogonUser property during an administrative installation. The installer never uses this property and a user never needs to modify it.
