Summary Property Descriptions
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 |
|---|---|
| Title | A description of this file as an installation package. The description should include the phrase "Installation Database." |
| Subject | The name of the product installed by this package. This should be the same name as in the ProductName property. |
| Author | The name of the manufacturer of this product. This should be the same name as in the Manufacturer property. |
| Keywords | A list of keywords that may be used by file browsers to do keyword searches for a file. The keywords should include "Installer" as well as product-specific keywords. |
| Comments | Contains the phrase: "This installer database contains the logic and data required to install <product name>." |
| Template (REQUIRED) | The platform and languages compatible with this installation package. See Template for syntax. |
| Last Saved By | Developers of database editing tools may use this property during the development process to track the last person to modify the 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. |
| Revision Number (REQUIRED) | Contains the package code for the installer package. |
| Last Printed | May be set to the date and time during an administrative installation to record when the administrative image was created. |
| Create Time/Date | The time and date when this installer database was created. |
| Last Saved Time/Date | The current system time and date at the time the installer database was last saved. Initially null. |
| Page Count (REQUIRED) | Contains a value used to identify the minimum installer version required by this installation package. For example, if the package requires at minimum the 2.0 version of the installer, this property should be set to an integer of 200.
Note: |
| Word Count (REQUIRED) | The type of the source file image. Stored in place of the standard Count property. This property is a bit field. See the Word Count topic for the values. Starting with Windows Installer version 4.0 on Windows Vista, this property includes bits to specify whether elevated privileges are required. |
| Character Count | Null |
| Creating Application | Contains the name of the software used to author this installation database. |
| Security | The value of this property should be 2 - Recommended read-only. |
| Codepage | The numeric value of the ANSI code page used to display the Summary Information. This property must be set before any string properties are set in the summary information. |
Transforms
