Changing the game's text language to English
Solution 1:
Also there is a way to change the text language if your copy is regionblocked like mine, which only has russian text available no matter how many other lang files are in the folder. It won't let you pick another, and if you leave only the en file it says there are no supported languages available. So what you need to do is rename both en files to ru(i'll give the example for my own language, others work similar). But that isn't all, you need to edit them for the game to work. I used Notepad++ for this. You open them, and replace, without quotes, "/en/" with "/ru/" in both files. After that you just save them and run the game, enjoying the english text.
Solution 2:
You have to search for an additional download in Origin.
Search for "Dragon Age Inquisition dubbed in English" or something similar in the store. You have to fake a purchase of this dlc (it's free) and to download 2,61 GB of additional data.
