Reading AppData Path for Current User in Remote Machine

Hi,

When I am logged in a remote machine, I can read the AppData path of the current user by reading remote registry. But if other user is logged in into that remote machine, remote registry returns "null" for the key "AppData". I have admin privilege in that remote machine. How can I get the current user's AppData path for remote machine? Please refer the code below.

            RegistryKey ProgramDirKey = RegistryKey.OpenRemoteBaseKey(
                    RegistryHive.CurrentUser, txtComputerName.Text).OpenSubKey(
                    @"SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders");
            if (ProgramDirKey == null)
            {
                MessageBox.Show("Could not open remote registry.");
                return;
            }
            object AppDataPathObj = ProgramDirKey.GetValue("AppData");
            if (AppDataPathObj == null)
                MessageBox.Show("Key AppData does not exist.");
            else
                MessageBox.Show("Value for AppData: " + AppDataPathObj.ToString());
            ProgramDirKey.Close();

Thanks,
