You have a quotation, so yes not simply a-z alphabetic symbols only. Try making a new user account on your laptop or pc with administrator privileges with only velia, no quotes no - dash just letters
Code:
C:\Users\velia\Documents\Elder Scrolls Online\live\AddOns
Then after you start the game and go through the setup, because it's a new user profile for windows, then accept the tos and all that, and completely log into a character. Then log out to let the game make folders and save things.
Then see if the new path above has an addons folder.
