If you encounter this issue, follow the steps below to troubleshoot it effectively.
Before You Begin
Understand the context: This issue often occurs in games using non-standard Steam libraries or executables, which can trigger compatibility or security warnings.Temporarily disable antivirus software if it is blocking important files. Re-enable it once troubleshooting is complete.Back up your game files before making any changes to avoid data loss.
1. Restore Blocked DLL Files from Antivirus Protection History
Security software may mistakenly block or quarantine overlay-related DLLs, causing this error. Restoring these files can help if they were flagged in error.
2. Install Steam and Enable the Overlay
Some games using custom libraries may still require Steam’s background services. If Steam isn’t installed or the overlay is disabled, DLL loading errors may occur.
3. Reinstall or Replace Game Files
If the problem persists, the game files may be incomplete or damaged. Reinstalling the game can ensure that all required libraries are present.
