我一直在尝试将微软访问数据库文件连接到我的Visual Basic应用程序。当我尝试运行应用程序时，我得到一个错误:"Microsoft.ACE.OLEDB.12.0"提供程序未在本地机器上注册";我用的是Microsoft visual basic 2012。

Public Class purchases
Private Sub Purchases_fileBindingNavigatorSaveItem_Click(sender As Object, e As EventArgs) Handles Purchases_fileBindingNavigatorSaveItem.Click
Me.Validate()
Me.Purchases_fileBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.TNJ_Retail_Management_SystemDataSet)
End Sub
Private Sub purchases_Load(sender As Object, e As EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'TNJ_Retail_Management_SystemDataSet.Purchases_file' table. You can move, or remove it, as needed.
