DREADMOOR: Fix for Error 11c7 (Workarounds)
Short answer
Suggested fix (unconfirmed): Disable Smart App Control in your Windows Start Menu, or verify your game files through the Steam library settings.
How to fix it
Turn off Smart App Control
- Open the Start menu.
- Type Smart App Control and launch the utility.
- Locate the option to disable Smart App Control and turn it off.
- Try launching DREADMOOR again.
Let Windows Defender update
- If you prefer not to keep Smart App Control disabled, you can wait for Windows Defender to receive its next definition update (usually a few days after the game’s release).
- After the update, start the game to see if the error disappears.
Re‑install the game
- If the error returns after a Windows update, uninstall DREADMOOR from Steam, then reinstall it.
- This often clears any residual files that might be flagged by Smart App Control.
If it still doesn't work
- Check for future Windows updates – a later Defender definition may finally stop flagging the game.
- Monitor the Steam forums – other players may share new workarounds as they appear.
- Consider a clean Windows Defender reset – resetting the security suite can sometimes clear persistent false positives (use the built‑in reset option in Windows Settings).
These steps are the most commonly reported ways to get past error 11c7 until an official fix is released.

What players suggest
It usually fix itself a few days after launch, once Windows Defender updates itself. If it does get fixed and it happen again, a quick game reinstallation should do the trick. That's at least what I do on my side with these sorts of things, and it works.
Game fail to launch after update (Conflict with Windows Smart App Control) Hello, After the latest update, the game fails to launch due to a conflict with Windows Smart App Control (CreateProcess() returned 11c7). Disabling Smart App Control resolves the issue temporarily, but could you please review the update file or code signing so it doesn't trigger this conflict? Thank you!
I now can't play the game after the update, getting this error. GUYS DO NOT TAKE THEIR ADVICE AND TURN OFF SMART APP CONTROL!!
