Swordeye blocked by Windows Smart App Control (fix)
Written by

September 23, 2026
On launching Swordeye, Windows shows a notification that Smart App Control (or Windows Defender) has blocked part of the app; the game still starts and appears to run normally afterward.
Also appears as: swordeye smart app control has blocked part of this app, swordeye windows defender blocked, swordeye virus warning, swordeye blocked by windows, swordeye smartscreen
This is a Windows security feature, not damage to your game files or an actual virus — reported independently by more than one player during Swordeye's PC playtests. When a player asked in Steam Discussions whether a launch-time popup meant the game had a virus, developer castavernas said there was no way it was related to Swordeye itself and guessed it was a one-off; a second player then reported the same Windows Defender / Smart App Control block on two separate launches and linked Microsoft's own "Smart App Control has blocked part of this app" support page, which points at an unsigned driver or DLL as the likely cause. The developer asked for a screenshot and the Windows Event Viewer log to track down the specific file, but no root cause or permanent fix has been confirmed as of this writing.
Fix it, step by step
Check whether the game still launches after the notification
Check whether the game still launches and runs after the notification — in every reported case so far it has. If so, this is Windows blocking one component (commonly an unsigned driver/DLL bundled with an Unreal Engine game), not a corrupted install.
Find what was blocked in the Event Viewer SmartAppControl log
To find exactly what was blocked, open Event Viewer (Windows key, type "Event Viewer") and check Applications and Services Logs > Microsoft > Windows > SmartAppControl > Operational, per the developer's own troubleshooting request in Steam Discussions.
- NoteReported
Report it with that log detail (and your GPU/CPU) in the Steam Discussions bug thread or the official Discord's #bug-reports channel — the developer is actively trying to identify the specific file Smart App Control is objecting to.
Sorted. Glad that worked.
