When people ask for help with a problem the answer many times will depend on what version of TES5 you are playing. Between SSE and SSE AE and the GOG versions I have lost count of how many versions of this game there are. I am sure somebody out there knows and could tell me.
To find out what version you are playing go to your games main folder, select SkyrimSE.exe or the equivalent right click on it, select "properties", select "details" and it will show what version of the game you are playing. When asking a question the version you are playing should be one of the first facts you should state. If you do not select the exe you will get a different menu.
