Cozy Game Restoration: Windows Smart App Control Blocks It with Error 0x11C7 (Workarounds)
Short answer
No confirmed fix yet. Players suggest: I've seen this happen on other indie titles too and they get it fixed once it is brought to their attention.
The problem
Smart App Control is blocking the game from launching. I'd like to keep it turned on. Is there a fix or recommended next step?
What players suggest
The dev will need to properly sign the app and build a reputation for it in Microsoft's cloud intelligence. I've seen this happen on other indie titles too and they get it fixed once it is brought to their attention.
You can temporarily disable Windows Smart App Control while you play and then turn it back on afterwards.
Just an update, it is now working after 24 hours.
Did this work for you?
