You are opening the subkey as read-only. You need to pass in true as the second param to write to it.

private void setAsDefaultScreenSaver(string valuePath)
{
       RegistryKey key = Registry.CurrentUser.OpenSubKey("Control Panel\\Desktop",true);

       if (key == null)
         return;
       else
       {
          key.SetValue("SCRNSAVE.EXE", valuePath); 
          key.SetValue("ScreenSaveActive", "1");
       }
       key.Close(); //close the key and flush it to disk


 }
