Microsoft Orca

imageOrca is a Windows Installer package editor provided as part of the Windows Installer SDK and designed to provide full access to the database tables that compose a Windows Installer package. While Orca provides powerful access to all features of the Windows Installer, it is not intended to replace a full-featured package-authoring environment.

One measurement you could use to see how experienced your “Application Packager” is, is to ask “Have you ever used Orca?”.

If the answer is “No”, or “What?”, they might not be as experienced as they claim.

The oldest copy of Orca I have is version 3.1.4000.1830, dated March 2005.
