以非管理员身份运行、读取注册表时，提示"不允许所请求的注册表访问权。"

1）以管理员身份运行、读取注册表时，顺利通过；
2）以非管理员身份运行、读取注册表时，提示"不允许所请求的注册表访问权。"

请问代码有何问题？.net 4.5

    Private Sub frmMain_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load

        '提示信息
        Dim strMsg As String = Nothing

        Try

            '注册表子项
            Dim SubKeyName As String = "HKEY_LOCAL_MACHINE\SOFTWARE\TSCU\config.ini" '

            '注册码键值
            Dim keyValue As String = Class1.ReadRegistry(SubKeyName, False)

            If keyValue IsNot Nothing Then

               strMsg = String.Format("值为：{0}", keyValue )     

            End If

        Catch ex As Exception

            strMsg = String.Format("{0} raised exception：{1}", ex.Source, ex.Message)            

        End Try

        MessageBox.Show(strMsg, "提示"， MessageBoxButtons.OK, MessageBoxIcon.Information)

    End Sub

<RegistryPermissionAttribute(SecurityAction.PermitOnly, Read:="HKEY_LOCAL_MACHINE\SOFTWARE\TSCU\config.ini")> '
Public Class Class1

    'Access the registry.
    Public Shared Function ReadRegistry(ByVal SubKeyName As String, ByVal flag As Boolean) As String

        '提示信息
        Dim strMsg As String = Nothing

            Using retkey As RegistryKey = Registry.LocalMachine.OpenSubKey("SOFTWARE\TSCU\config.ini", True)

            '返回
            Return retkey.GetValue("CDKEY")

        End Using

    End Function

End Class

Using retkey As RegistryKey = Registry.LocalMachine.OpenSubKey("SOFTWARE\TSCU\config.ini", True)

修改为：

Using retkey As RegistryKey = Registry.LocalMachine.OpenSubKey("SOFTWARE\TSCU\config.ini", False)

读取成功了，同样情况，在非管理员运行时，写入注册表失败，求解？

<RegistryPermissionAttribute(SecurityAction.PermitOnly, ViewAndModify:="HKEY_LOCAL_MACHINE\SOFTWARE\TSCU\config.ini")> '

没有权限就不让写入,这种情况是正常的吧
