需要一些诊断SEHException的帮助外部组件引发了异常

如何解决需要一些诊断SEHException的帮助外部组件引发了异常

使用VB.Net和VS2012的Windows Forms应用程序。使用Access Runtime 2013连接到Access数据库。该应用程序已编译为目标x86。该问题是间歇性的，随机出现在多台不同的PC上，并访问本地硬盘上的数据库。

Using cn As New OleDbConnection
  System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.WaitCursor
  If Not OpenDBConnection(cn) Then
      System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.Default
      MsgBox("Unable to make database connection to update screen status.",MsgBoxStyle.OkOnly,"Database Connection Error (MMUN1)")
      Exit Sub
  End If
'continue processing....
 end using

Public Function OpenAccessConnection(ByRef conn As OleDb.OleDbConnection) As Boolean
    Dim builder As New OleDbConnectionStringBuilder()

    'conn.Provider = "Microsoft.ACE.OLEDB.12.0"       
    Try
        builder.ConnectionString = "Data Source=" & dpath & dbnAME
        builder.Add("Provider","Microsoft.ACE.OLEDB." & ACCESsveR & ".0")  'ACCESsveR is '12'
        conn.ConnectionString = builder.ConnectionString
        System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.WaitCursor
        conn.open()
        System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.Default
        Return True
    Catch ex As Exception
        MsgBox("Unable to make Access connection.  Error# " & Err.Number & " " & ErrorToString() & " " & ex.ToString,"Database Connection Error (OLEOPN1)")
        Return False
    Finally
        builder.Clear()
        builder = nothing
    End Try
End Function

Public Function OpenDBConnection(ByRef conn As OleDbConnection) As Boolean
'I kNow this is an extraneous function call but it is in transition from multiple prior uses and I thought I had better not exclude it from this post in case it mattered for some reason
    OpenDBConnection = OpenAccessConnection(conn)
End Function

我已经阅读了许多有关此主题的文章，但没有找到解决方案，并且坦率地说，我不确定在哪里寻找。难道是来自较早的应用程序错误？线程/ STA问题？如果是这样，我该怎么办？在开发机器上，有时我会看到disconnectedContext错误，但没有看到运行发行版的PC上出现的外部组件错误。这些有关系吗？同样，有一些到数据库的ADO（ADODB）连接（仍在尝试替换/升级），但是在建立新连接时这些连接没有打开。但这可能是连接池问题吗？预先感谢您提供的任何帮助。
