控制台应用程序在应用程序中抛出异常但在调试中没有

Question

运行此简单代码时，每次在控制台应用程序中都会引发异常

    Public Function convertWord(ByVal file As String, ByVal Path As String) As Integer

    Dim convertObj As Microsoft.Office.Interop.Word.Application
    Dim WordDoc As Microsoft.Office.Interop.Word.Document

    Try
        convertObj = New Microsoft.Office.Interop.Word.Application
        WordDoc = New Microsoft.Office.Interop.Word.Document
        WordDoc = convertObj.Documents.Open(Path)
        WordDoc.ExportAsFixedFormat(file, WdExportFormat.wdExportFormatPDF)
        Return 2
    Catch ex As Exception
        _checkLog("Originalna greška je : " & ex.Message & ex.StackTrace)
        Return 5
    End Try

End Function

如果我使用调试模式，这个功能就完美了。否则

Log check: 30.12.2015. 11:17:15 Originalna greška je : Object reference not set to an instance of an object. Line 34

第 34 行>>>WordDoc = convertObj.Documents.Open(Path)
