Dragon Age Inquisition doesn't start?

Well, I don't know if anyone has posted this here already, but I just figured it might perhaps help some people who had this issue for the same reason as myself and a friend of mine for whom this solution worked just fine, too.

I am playing on a notebook with a NVIDIA graphics card and (just) a dual core processor. The processor has nothing to do with the problem, at least not in my case or the one of my friend.

What me and her needed to play was the NVIDIA Game Ready Driver. I would post a link, but I'm only able to find the German site, so just google and install it. If you do not already have it installed, you need the NVIDIA GeForce Experience first.
For the graphics card of the friend I mentioned, the Game Ready Driver was not recommended which is why her graphics card told her, there would be no newer driver available. She tried it anyway and it worked out. I am not saying that this will work all the time and that there's no risk if according to NVIDIA, the driver is not for your card spefically, all I'm saying is that it worked for her and it might be worth a shot.

I don't know if this will help anyone and I'm sure there are plenty of other reasons why this error might occur. I really hope you all find a solution soon if this here does not work for you.
