.NET in VBA

[NooS]

I working with vb.net 2005. I created a Class Library project and add a COM
Class to the project. I set COM interoperability, and COM visibility of the
project.
Also I set a strong name of assembly.
I compile all in a dll file.
Now, if I refer it in Excel 2003 VBA macro I view method and properties
correctly, but if I run the macro, VBA say me that dll class not found.
Why?

Have you stored the assembly in the GAC and registered it using Regasm? If
not, there is why you are not seeing it.

Now, I temporary copy the dll file in Excel.exe directory and VBA found my
library, but when I run the VBA macro now say me that "The format of file
'myDLL' is not valid".

In the .NET project COM interoperability, and COM visibility are correctly
setting.
What is wrong?
