title: How to register a legacy typelib (.tlb) on Windows 7?
body: <p>I have a new PC running Windows 7 and Visual Studio 2010, and need to register a legacy typelib (.tlb) to interface with an existing legacy application.  However, regtlib.exe does not seem to be part of Windows 7 (I don't think it was part of Vista either), and regtlibv12.exe, available as part of Visual Studio 2005, seems to have disappeared with Visual Studio 2008 (and certainly Visual Studio 2010).</p>
  
  <p>Microsoft forums and knowledge base articles refer to RegAsm.exe.  I've tried RegAsm.exe, but that will only create and register a typelib from an existing dll or assembly (which I do not have).  I can't believe there is no way to register an existing typelib on Windows 7.  Any help would be most appreciated.</p>
