If you want to move the NXT-OS desktop use the "Move desktop skins to" drop down. You can move Overlay, Lock Screen, and Notifications by choosing another monitor in "Main Monitor" dropdown. To fix this issue you can delete both the "NXT-OS" and "NXT-OS Data" folders in your Rainmeter skins folder.

If you are still haveing this problem it is possible that you already have NXT-OS installed on your machine.

Try running the rmskin file again to see if the issue persists. If the insaller did not appear after pressing the install button it is possible that you did not leave the "Load Included Skins" checkbox checked. Once you have gone through the installer click "Finish" to go to the NXT-OS desktop.
