Re: Unable to launch Mass Effect: Legendary Edition
The most common cause for EA games to not launch without an error is interference from other software. Usually this is antivirus software, so pause your antivirus software to see if the game launches. If that works, the long-term solution is to add your game and EA folder to the excluded folders of your antivirus software.
If disabling antivirus doesn't work, there could still be interference from other software. In that case, clean booting Windows with a minimal number of background processes might make the game run (more info here). If that helps, you'll have to figure out which background application was interfering by re-enabling them until the game doesn't launch anymore.
