Hello,
I have the same problem described in this thread. I am trying this on Visual Studio 2010 with Crystal Reports 13 (for VS.NET). I have done all the steps as described in tutorial:

Also in this ebook, page 390:

However my class and functions are not showing up in Crystal Reports Designer (Formula Workshop > Functions > Additional Functions). I verified that my DLL, named CRUFLICE.DLL, is registered with COM. I have an older VB6 DLL which, if I register it with COM, then it's functions do show up. So I renamed my VB.NET class, methods, assembly, to match the old DLL and still no luck. I would do C# but the new .NET custom functions are going to replace the old VB6 custom functions, so I am doing it in VB.NET so can reuse some of the old code.
My new DLL is 8 letters long starting with CRUFL prefix. My class is ComVisible and has a Guid and implements an interface. My functions are public and return a String. I have registered DLL through Visual Studio build option and directly with regasm and gacutil. What else am I missing?
Thanks.
