The DLL does not show in the list and I think I know why. After hours of google searches I found a number of references to visibility of .NET components to non-.NET languages.

These refer to the use of REGTLIBv12.exe and REGASM.EXE .

I have .NET 4.5.1 installed and both programs are in the folder C:\Windows\Microsoft.NET\Framework\v4.0.30319\.

Can you confirm that I need to run these on the .TLB and .DLL files and whether the order of running is significant?

Thanks for your assistance
