Re: DA:I won't launch in EA app
I know it will work if everything is correct on your PC, as it works on mine after a few things done. For me it was do a repair of install after the change over, and sadly every game in my library that was installed needs to be repaired before they will work. Second thing I did for DAI was to set a global exception in my anti-virus(AVG) to ignore the game completely. Once I did these two things, the game launched normally.
If these don't work for you, then maybe post up a DXDiag file to show a bit about your system, and list anything else you have tried as well. Also do you use Mods or the mod launcher to run the game??
