Exception has been thrown by the target of an invocation

Hi everyone. I'm making a multiform program here, and one problem I've discovered is, Visual Studio seems to not want to go to the heart of my problem here, instead it seems to stop right where my main form opens a different one.

The thing here is, I want to pass all focus onto that new form. I want it to be the main form, and I want the previous one to be forgotten about. I would also like the debugger to get comfortable with this form. Here's the code that opens up the second form:


Try

            SetupGuide.Show()

        Catch ex As Exception

            MsgBox("Caught error: " + vbNewLine + vbNewLine + ex.ToString)

        End Try

        Me.Close()

The problem is, it never catches the exception there, but the built in VS debugger somehow does, halting my program with all of the details on why this invocation failed.

So really, my main issue now is how I change this from being an invocation, to more being a passing of control. Also, here is the entire exception:


System.Reflection.TargetInvocationException was unhandled

  Message="Exception has been thrown by the target of an invocation."
