Addon button missing

I have just reinstalled wrath classic after getting my pc fixed and although it is a clean install on a freshly wiped pc i am not seeing and addon button ingame, when i try to install addons through curseforge it can’t find the game and when i try to do it manually it says file path does not exisit.

When i go into the wow files through windows explorer i can see the addon folder so i tried doing it the old school way of downloading the files individually and extacting them then copy and pasting the addons in to addons folder but when i open the game still nothing .

What’s the file path you’re putting them in?
