It's not the UserSettings.txt!
It's the same folder but the AddOnSettings.txt file!
The file will be created after first login to the game and after choosing a character and login to the ingaem world, as far as I remember.
After talking to Croshy he also created a OneDrive link with the addons and libraries he uses, for accessibility, and the libraries (dependencies) so you can download the whole addns folder and put them into your
c:\users\your windows username\
folder.
Here is the link for you guys:
https://onedrive.live.com/?authkey=%...A8341E8780C731
The last update date is shown at the link's OneDrive folder name now, in order to see if there have been any changes to the package, or not!
Croshy will update it with the newest versions here and there, if there were any updates.
If you download this and copy the "Copy this into ..." folder contents of that folder to your c:\users\your windows username\ folder, overwriting the addons that you already got there, you will have some addons like
AddonSelector
FCO Accessibility
Potion Warner
LibAddonMenu
WaypointIt
and others
You need to login the once and go to the ingaem world, then logout!
After that you can then change the file live/AddOnSettings.txt and switch the entry for "Addon Selector" to 1 at the #Default entry.
And "Votans Addon Menu" should be enabled with 1 too so your libraries/dependencies will be automatically enabled once you click on addons.
That way you should, after next login, have the way to type
/addons
into the chat to open the addon manager with that.
And then hopefully NVDA or oher OCR tools can help you for the moment to find the addons and enable them.
And you can click the addon names then too instead of only the small checkboxs, to enable or disable them.
