These methods aren't guaranteed to work for everyone, but they're worth trying and could be a quick way to get back into the game without much hassle.

If you're encountering error code 664 while playing Dark and Darker, here are several troubleshooting steps you can try:

Basic Steps:

• Restart and Run as Administrator: Shut down your system, reboot, and launch the game as an administrator. This can often resolve minor software glitches that might be causing the error.
• Check Network and Servers: Ensure your internet connection is stable and that the game's servers are online. Use third-party server status pages or the game's official forums for reference. If the servers are experiencing downtime or maintenance, you'll need to wait until they're back online.

Advanced Troubleshooting:

• Use a VPN: If you suspect network-related issues or regional restrictions are causing the error, consider using a VPN. A VPN can route your internet traffic through a different server, potentially bypassing any limitations or interference.
• Firewall Exceptions: Firewalls, both on your router and within your Windows settings, can sometimes block necessary game connections. To ensure Dark and Darker can communicate properly, add the game's executable files to the list of allowed programs in your firewall settings.
• Verify Game Files: Corrupted or missing game files can lead to various errors, including code 664. To check for any issues, verify the integrity of your game files through Steam. This process will scan your game files and replace any corrupted or missing ones.
• Update Everything: Keep your game, Steam client, operating system, and GPU drivers up to date. Game developers often release patches and updates to address bugs and improve performance. Outdated software can sometimes contribute to errors.

Additional Tips:

• Check for Third-Party Software Interference: Some third-party programs, such as antivirus software or overlays, can interfere with game processes and cause errors. Try temporarily disabling any non-essential programs to see if the error persists.
• Consult the Game's Community: If you're still having trouble, visit the Dark and Darker forums or community channels. Other players may have encountered similar issues and can offer additional advice or solutions.
