Reggarding the previous post, is there a way to do a clean unninstal of previous versions?
You appear to be doing something very wrong, although I'm not sure what. I would suggest that you get tech support on the AGOT discord.
How did you actually install the mod in the first place? Did you use the installer, did you install it manually via the zip file download, or did you subscribe to the mod on the Steam Workshop?
I deleted the folders inside the documents/paradox/ck2 both there and the one inside the mod and it didn't help
What do you mean by "the one inside the mod"? That doesn't make any sense.
Assuming you used either of the non-Steam Workshop download options, to completely remove the previous version of the mod, you need to delete the "A Game of Thrones" folder and .mod file in Documents/Paradox Interactive/Crusader Kings 2/mods. Additionally, it may also be necessary to delete the gfx folder in Documents/Paradox Interactive/Crusader Kings 2.
If you downloaded it through Steam then you need to follow the same steps, but also unsubscibe from it on Steam, and then resubscribe after restarting your computer.
If all else fails, make a backup of the savegames and mods you want to keep (their mod folders and .mod files in in Documents/Paradox Interactive/Crusader Kings 2/mods), and then completely delete your in Documents/Paradox Interactive/Crusader Kings 2 folder and its contents. Make sure that you've unsubscribed from everything on the Steam Workshop, restart your computer, and then start up CK2, and the in Documents/Paradox Interactive/Crusader Kings 2 folder will regenerate automatically. Quit the game, and place your copied savegames and mods back in their locations.
Now I'm trying to unninstal it as if it were a regular program
What? The AGOT mod is not a program, although it can be installed using an installer. If you try to "uninstall it as if it were a regular program", then all you'll do is delete the launcher.
