Hello. There is a vast amount of information on this forum. I've attached it for you. Please try these first.This specific DirectX error actually happens on non-English Windows setups because the game's title ("Battlefield 3™") contains a trademark symbol that causes encoding conflicts on certain regional settings.The forum logs show this bug has been around for 12 years. The official, verified Solved archive can be found here:
Battlefield 3 Is Not Opening | EA Forums - 13502227
To fix this, please follow these exact steps:
1. Open your Windows Control Panel.
2. Go to "Clock, Language, and Region" -> "Region".
3. Click the "Administrative" tab.
4. Under "Language for non-Unicode programs", click "Change system locale".
5. Set it to "English (United States)" and click OK.
After a quick PC restart, the DXGI_ERROR_INVALID_CALL error will disappear completely and your game will launch normally. Don't worry, this will not change your main Windows display language!
