I have a (VS 2008) C# project that needs to use a 3rd-party COM object. For that, I'm told, I need to register the COM objects's tlb file. So I do
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\regtlibv12.exe blahblah.tlb
which gives me
Registration of FREngine.tlb successful.
But then I can't add a reference to it in the C# project, because it the type lib isn't available on the "Add Reference" dialog's COM tab. Sure enough, a registry search for blahblah comes up empty.
Anyone out there any idea what should I be poking at next?
