Fsociety for PUBG (Steam, PC) — installation and launch guide
Preparing Windows, disabling Defender and anti-cheats, the correct loader launch order, pressing F5 in-game, and fixes for the timestamp / bad_timestamp / session_invalid errors.
Compatibility
Supported Windows: works on any build of Windows 10 and on Windows 11 up to build 26200.8037 (inclusive). On newer Windows 11 builds the cheat will not load.
Check your build: press Win + R → type winver → Enter.
26200.8037 inclusive.Before launch
Prepare Windows once. Without these steps the system will block the software.
Step 1. Disable Windows Defender
Start → "Windows Security" → "Virus & threat protection" → "Manage settings". Turn off all four switches:
- Real-time protection — Off
- Tamper Protection — Off
- Cloud-delivered protection — Off
- Automatic sample submission — Off
Step 2. Disable third-party antivirus
Kaspersky, Avast, ESET, Bitdefender, Norton, McAfee, AVG, etc. — fully disable or temporarily uninstall for the duration of the session.
Step 3. Run as administrator
Right-click the downloaded loader → "Run as administrator", confirm the UAC prompt.
How to launch
Follow this order every time — breaking the sequence leads to a load error.
Step 1. PUBG must be CLOSED
Do not run the loader while PUBG is running.
Step 2. No anti-cheat processes
Open cmd as Administrator and run these in turn:
sc stop faceit
sc stop vgc
sc stop vgk
taskkill /F /IM FACEITClient.exe
taskkill /F /IM vgc.exe
taskkill /F /IM vgtray.exeIf a service is not found, that's fine — it just isn't installed. The key point is that none of the listed processes are running.
Step 3. Run the loader and click Load
Wait for the Loaded successfully message. Do not close the loader window — it must stay open for the whole gaming session.
Step 4. Launch PUBG
Start PUBG and press F5 in the game menu. The overlay and ESP will activate.
Step 5. If ESP doesn't render in a match
Close the game and restart the software, then repeat the launch order from Step 1.
Common issues
❌ Error: timestamp / bad_timestamp
Your computer clock is out of sync with the authorization server.
- Start → "Date & time".
- "Set time automatically" — On.
- Click "Sync now".
- Make sure the time zone is correct for your region.
- Restart the loader.
❌ Error: session_invalid
The session expired or the key was used on another device. Fix:
- Fully close the loader.
- Run the loader again as administrator.
- Re-enter your key.
If the error persists, contact the seller to reset the session.
❌ The loader won't start / closes immediately
- Make sure Windows Defender and third-party antivirus are fully disabled (not just "paused for 10 minutes").
- Run the loader as administrator — without it the injector cannot load its modules.
- Check your Windows 11 build: if it is above
26200.8037, the cheat is not supported — wait for a developer update or roll the build back.
timestamp / session_invalid errors are easiest to solve with this guide.
