How to register a legacy typelib (.tlb) on Windows 7?

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).

Microsoft forums and knowledge base articles ref开发者_Go百科er 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.

Well, I guess I can answer my own question (and for anyone else who has the same problem):

Apparently, regtlibv12.exe is part of Visual Studio 2010 (contrary to what I read on various Microsoft forums), but it is located in the Windows\Microsoft.NET\Framework\v4.0.30139 folder (not the v2.0.50727 folder). Using that executable I was able to successfully register the legacy typelib (.tlb).

It comes with .Net framework installation. On my machine I found it as:

C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\regtlibv12.exe
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regtlibv12.exe

There is also C:\WINDOWS\REGTLIB.EXE that seems to be part of a standard Windows 7 installation.

From a Developer Command Prompt for VS2013, you can use the regtlib.exe command.

To find the Developer Command Prompt for VS2013 you can try looking under Start -> All Programs -> Visual Studio 2013 -> Developer Command prompt for VS2013.
