Specifying a Primary Key for the Registry Table

InstallShield 2026

Project: This information applies to the following project types:

• Basic MSI
• DIM
• InstallScript MSI
• Merge Module
• MSI Database
• MSM Database
• Transform

To specify a primary key for a registry key or value:

1. Right-click the key or value and click MSI Value. The MSI Value dialog box opens.
2. Enter the name of the key. Since the primary key must be a Windows Installer identifier, the name may contain only letters, numbers, underscores (_) and periods (.), and it must begin with a letter or underscore.

To view or modify the primary key, right-click the registry key or value and click MSI Value again.

If you do not specify a value, InstallShield generates a unique primary key for this entry in the Registry table.
