I'm trying to build my first Add-in (using VB.NET) for use with MS Access.
It's set to load with Access, but when I open Access, I get a messagebox 
saying:

Unable to cast COMobject of type 'System.__ComObject' to interface type 
'Microsoft.Office.Core.CommandBar'.  This
operation failed because the QueryInterface call on the COM component for 
the interface with IID
'{000C0304-0000-0000-C00-000000000046}' failed due to the following error: 
No such interface supported (Exception from
HRESULT: 0x80004002 (E_NOINTERFACE)).

Can someone give me an idea in beginner's terms what the problem might be??

TIA
