How can I retrieve the name of the .msi file being installed?

In a VS.Net setup project there are variables such as ProductName and TargetDir, but is there a way to use the setup's .msi filename in a registry entry? [ProductN开发者_JAVA百科ame] can be used in the registry view registry entries, but I want to put the .msi filename being used in the registry.

The name of the .msi file used to start the installation is stored in OriginalDatabase property.
