🚨 Troubleshooting & FAQs


🛑 Missing Visual C++ Redistributables & DLL Errors

Symptom: Server fails to launch or throws an error stating MSVCP140.dll or VCRUNTIME140.dll missing.

Solution: Install the official Microsoft Visual C++ Redistributable Package (x64): Microsoft C++ Redistributable Download Link


🛡️ Windows SmartScreen & SAC Warnings

As an independent community project without a paid Microsoft Digital Signature, Synix may trigger security prompts on new Windows installations:

  • Windows SmartScreen: Click More Info -> Run Anyway.
  • Windows 11 Smart App Control (SAC): SAC blocks unsigned executables entirely. If enabled, set SAC to 'Evaluation' or 'Off' to run community tools like Synix.

🧱 Windows Firewall & Administrator Access

User-Mode Sovereignty (No-Admin): Synix runs entirely in User-Mode without requesting Administrator (UAC) privileges by default. It will not edit your Windows registry or modify host system settings.

Firewall Requirements: Because Synix runs without Admin privileges by default, Windows Defender Firewall may prompt you the first time a game server binary executes. Always check 'Allow on Private and Public Networks' when prompted by Windows.

Smart Firewall Cleanup (Optional): If you enable the 'Run as Administrator' toggle in the Settings window, Synix can perform advanced system tasks. Currently, this allows Synix to use Just-In-Time Elevation to automatically find and delete orphaned Windows Firewall rules when you permanently delete a game server. If you decline the Windows UAC prompt, Synix gracefully skips the task and continues normal operations.


💾 Locating & Restoring Server Backups

Where are my backups? By default, all automated ZIP backups created by Synix are stored at: C:\Synix\BackupGames\[Game_Name]\{Server_Name}\

If you have activated a Custom Backup Location in the Synix Settings menu, your backups will be routed to that specific drive or folder instead.

Note: Synix actively monitors this folder and will automatically delete the oldest backup if your rolling 'Max Saved Backups Limit' (configurable in Settings) is reached.

Restoring a Save: You can extract any ZIP directly over your active server folder to restore previous world saves.
