Error when calling VBA function from VSTO code

Question

I have the following VBA code in a module of one of my .xlt files:

Public Sub SetShapeTop(ByVal shapeName As String, ByVal topValue As Single)
  ThisWorkbook.ActiveSheet.Shapes(shapeName).Top = topValue
End Sub

In my VSTO add-in, I have the following C# code which tries to call that VBA function:

m_worksheet.Application.Run("SetShapeTop", kv.Key, kv.Value, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
  Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
  Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
  Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

That line throws an exception, as follows:

(Excerpt from my log4net logs)

[Exception: COMException]

{Parameters: }
{Message: Cannot run the macro 'SetShapeTop'. The macro may not be available in this workbook or all macros may be disabled.}

Am I missing something here? If anyone can point me in the right direction, I'd really appreciate it...!

This is a security restriction.

Go to Trust Center in Excel and check Trust access to VBA project object model.
