I have an Active X control that calls an Excel Template and attempts to run a method called "RunReport".

I have tried:
1) Checked to make sure that the path I am using is correct and that the file name is correct
2) I have made sure that the file name, module and methods do not have any underscores
3) Enabling all macros and "Trust access to VBA Project model" in the Trust section.
4) I have attempted to prefix the method name with its module name "Module1.RunReport" and tried "MyExcelTemplate.xltm!Module1.RunReport"
5) I have tried Removing and re-adding the Method (Saving and trying the file after each step).

Any help you can provide would be great.

Code Snippet:
Dim officeApp As Object = Nothing
Dim templateDocument As Object = Nothing

officeApp = CreateObject("Excel.Application")
officeApp.Visible = False

templateDocument = officeApp.Workbooks.Add(Template:=ReportParameters.ProcessTemplate)

extendedMethodName = "Module1.RunReport"

officeApp.Run(extendedMethodName, ReportParameters)

templateDocument.Close(SaveChanges:=False)

officeApp.Quit()
