Not Valid reference to the registry

[Priya]

Hi All,
I am working with OpenNETCF.Desktop.Communication dll to change the
registry of device from desktop.When i delete a key ,it is
throwing exception like "Not a valid reference to the registry" though the
key is there in the registry.
I tried with lot of options but it is giving the same problem.
Can you help me..
Thank you,
supriya

You're likely working with a WM 5.0 device and RAPI is not provisioned with
permissions to alter the registry by default on your device.

It is giving same problem in 4.2 version also.

//Create key under HKEY_USERS

private void btnCrtKey_Click(object sender, EventArgs e)

Just like is documented for the full framework and the CF, the
CreateSubKey(string) overload creates a key with _read_ permissions. You
cannot delete when you only have read permissions. Open it with write
permissions if you want to delete.
