Solution not working

Dear Govert
I am getting the run-time error '429': ActiveX component can't create object' with C# my solution which uses DNA to speak to Excel. I get this message in VBA when it tries to instantiate the .NET class. It all used to work fine till a few days ago. When looking for possible causes, I came across this solution of yours, which I tried. I still get the same error message. I guess it just shows that something has gone wrong on my machine, independent of the solution.

Would appreciate any help.

Thanks

Raj
