我正在尝试在Visual Studio 2012中编写一些Visual Basic代码，以便能够打开并更改现有的Microsoft Excel工作簿（Office 2010）。这是我提出的代码：
Dim BillingCalender As String = *Path to Excel Workbook*
Dim xlsApp As Excel.Application = New Excel.Application
Dim xlsWorkBooks As Excel.Workbooks = xlsApp.Workbooks
Dim xlsWB As Excel.Workbook = xlsWorkBooks.Open(BillingCalender)
但是，每当我尝试运行此命令时，都会打开一个新的Excel工作簿，并给出以下错误：
An add-in could not be found or could not be loaded

有人可以帮我理解问题是什么以及如何规避它？
