working with registry using vb.net

[minus0]

Hello all,

I wrote a couple procedures to go through the registry to search for a keyword but its failing midway through saying "Requested registry access is not allowed". I am running as a user with admin privileges and opened the registry as read/write, so what am i missing here?

Private Sub GetSubKeys(ByVal SubKey As RegistryKey) 
    Dim SearchWord As String 
    SearchWord = "SYMANTEC" 
    For Each innerKey As String In SubKey.GetSubKeyNames 
      Dim local As RegistryKey = Registry.LocalMachine 
' == line below is where it breaks ==    
  local = SubKey.OpenSubKey(innerKey, True) 
      If InStr(local.ToString.ToUpper, SearchWord) Then 
        sw.Write(local.ToString + Chr(13) + Chr(10)) 
        Exit For 
      End If 
      GetSubKeys(local) 
    Next 
   End Sub 

  Private Sub btnGetKeysDemo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGetKeysDemo.Click 
    Dim WhichRegKey As RegistryKey = Registry.LocalMachine 
    WhichRegKey = WhichRegKey.OpenSubKey("software", True) 
    GetSubKeys(WhichRegKey) 
    MsgBox("done") 
  End Sub

Thanks in advance
