I'm getting attached error "InvalidCastException" on a simple windows application using vb 2010 express and soliworks 2010.

I'm not able to connect to Solidworks object with the standard syntax:

swApp = CreateObject("SldWorks.Application")

I was able to get my code working using a dll addin but I was not able to debug it (due to vb express restricition...). So I tryed to debug it on an equivalent Windows Application but as you can see I'm not able to get SolidWorks Object...

Any idea or suggestion?

Thanks!
