Earlier today I released version 1.0.0 of RegTlb which is a command line tool for registering and unregistering type libraries.

COM Servers usually register their own type libraries, but this is not always the case and it may be convenient to register just the library without installing the actual COM servers. For example, a developer may want to target the contained types for a build, without wanting to install or run the code locally.

v1.0.0 It supports registration per-system or per-user It also supports querying a type library for info about its contents, and querying the registry for registration information for specific libraries. The reason for building this tool is that there is no built-in tool shipped with Windows for registering a type library. There is a tool that is shipped with some older versions of the .NET Framework or the Windows SDK, but it is hard to acquire as a standalone tool, and you’re not allowed to redistribute it. RegTlb is free to use and redistribute.

You can find the project page here.

Source code and executables are also available.
