Windows 7 and Reg Functions..

[GremlinSA]

i have two very simple functions... to load and save regkeys..

       Public Function Load(ByVal Regloc As Reg_type, ByVal Keyloc As String, ByVal Keyname As String, Optional ByVal DefValue As String = "NA") As Regkeys
            Dim TmpReg As New Regkeys
            Dim TmpVal As String
            TmpVal = DefValue
            Try
                Select Case Regloc
                    Case Reg_type.Current_Config
                        rk = Registry.CurrentConfig.OpenSubKey(Keyloc, False)
                    Case Reg_type.Current_User
                        rk = Registry.CurrentUser.OpenSubKey(Keyloc, False)

                    Case Reg_type.Local_Machine
                        rk = Registry.LocalMachine.OpenSubKey(Keyloc, False)

                    Case Reg_type.Users
                        rk = Registry.Users.OpenSubKey(Keyloc, False)
                End Select
                TmpVal = DirectCast(rk.GetValue(Keyname, DefValue), String)
            Catch ex As Exception
                RaiseEvent Int_Error(Error_type.Load_Err)
            Finally
                TmpReg.LoadReg(Regloc, Keyloc, Keyname, TmpVal)
                TmpReg.Changed = True
                Try
                    rk.Close()
                Catch ex As Exception
                End Try
                End Try
                Save(TmpReg)
                Return TmpReg
        End Function

        Public Sub Save(ByRef RegKey As Regkeys)
            If RegKey.Change Then
                Try
                    Select Case RegKey.RegType
                        Case Reg_type.Current_Config
                            rk = Registry.CurrentConfig.CreateSubKey(RegKey.KeyLoc)
                        Case Reg_type.Current_User
                            rk = Registry.CurrentUser.CreateSubKey(RegKey.KeyLoc)

                        Case Reg_type.Local_Machine
                            rk = Registry.LocalMachine.CreateSubKey(RegKey.KeyLoc)

                        Case Reg_type.Users
                            rk = Registry.Users.CreateSubKey(RegKey.KeyLoc)
                    End Select
                    rk.SetValue(RegKey.Keyname, RegKey.KeyVal)
                    RegKey.Changed = False
                Catch ex As Exception
                    RaiseEvent Int_Error(Error_type.Save_Err)
                Finally
                    rk.Close()
                End Try
            End If
        End Sub

these functions work fine in XP and vista, but when tested in Windows 7 .. the save reg function crashes... we assume it may be to do with Windows 7 having changed access to the reg... any ideas ???
