It had been awhile since I’d exported a TypeLib, so I had forgotten how! The world has moved on to .Net and its “tlxexp.exe” tool, which is for .Net/CLR assemblies only.
1) Download OLEVIEW.EXE the OLE/COM Object Viewer
2) Run OLEVIEW, then double-click the Type Library in question.

3) Copy the text of the Type Library to wherever you need it.
