Add-in excel not loading

Question

Hi,

A former college of mine has biuldt a add-in for excel. Unfortunatly he is not available any more and I'm set to finnish it. The project is buildt in visual studio 2005 team suite in vb.net. The add-in is for office 2003 and I have 2003 pro installed on my computer. When I try to debug the project inside VS a new instance of excel appers but non of the code in my project is excecuted (I tried setting a breakpoint in sub ThisAddIn_Startup). I know that my former college ran the plugin from within VS this way and I can't figure out why I can't do the same. Dotnet development is not my cup of tea but the changes I need to make are so small and if I could only get it to run I would be set.

I'm guessing there is some dll issues somewhere but I don't have a clue on where to start looking. I don't get any error messages.

My platform:

Win 2000
VS 2005 TS
Office 2003 pro


EDIT: The same thing happens if I try to create a new excel add-in project. When I debug excel is launched but I can't find the new add-in. If I put a breakpoint inside the startup method it says that the breakpoint will never be hit.

You might want to look at the following article

I'm guessing the problem might be with the VSTO loader...
