VB.Net COM error on accessing Form or form controls

I am trying to create a program that reads an MDB and identifies the forms and controls on the forms.  I have had soome success but I keep getting a weird COM error.  I am VERY new to VB but been a programmer for 20 years.

Anyway, I copied code from a microsoft article that does what I want to do.  THAT code blows up also!!  

I included what I copied from MS and Also the error message.  Is there a probelm with my setup or what??  This happens on two different macines, XP professional and Win 7 64 bit.

Here is the error I get:
Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.Office.Interop.Access.Form'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{66B22FB4-F70E-4F03-A00A-F76E9ADBBF10}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
