> Got a “no‑launch” error? Follow these simple steps and you’ll have your FiveM client up and running in minutes.

Prerequisites

• Windows 10/11 (64-bit)
• Updated graphics drivers
• Administrative privileges
• FiveM installed via official launcher

Diagnostic Steps

1. Check Crash Logs

Navigate to FiveM installation directory and locate crash dumps:

%localappdata%\FiveM\FiveM.app\crashes\

Open the most recent .dmp file timestamp to identify specific error codes.

2. Verify Game Cache Integrity

Grand Theft Auto V (Steam):

1. Right-click GTA V in Steam Library
2. Properties → Installed Files → Verify integrity of game files
3. Wait for verification (15-30 minutes)

Grand Theft Auto V (Rockstar Launcher):

1. Open Rockstar Games Launcher
2. Settings → GTA V → Verify Integrity
3. Complete verification process

Grand Theft Auto V (Epic Games):

1. Library → GTA V → Three dots menu
2. Manage → Verify
3. Allow process to complete

3. Common Solutions by Error Type

Error: “Could not find game executable”

cd /d "%localappdata%\FiveM\FiveM.app"
FiveM.exe -sp_BackupDirectory "C:\FiveM_Backup"

Then manually select GTA V directory when prompted.

Error: “Corrupted game cache”

Delete cache folders:

rmdir /s /q "%localappdata%\FiveM\FiveM.app\cache"
rmdir /s /q "%localappdata%\FiveM\FiveM.app\data\cache"

Error: “DLL injection detected”

Disable conflicting software:

• MSI Afterburner
• RivaTuner Statistics Server
• Discord overlay
• GeForce Experience overlay
• Windows Game Mode

Add FiveM to antivirus exceptions:

%localappdata%\FiveM\FiveM.app\FiveM.exe
%localappdata%\FiveM\FiveM.app\FiveM_b*.exe
%localappdata%\FiveM\FiveM.app\FiveM_ROSService.exe

4. Advanced Troubleshooting

Clean Boot FiveM:

1. Delete CitizenFX.ini from %localappdata%\FiveM\FiveM.app\
2. Launch FiveM while holding Shift key
3. Select “Safe Mode” when prompted

Reinstall Visual C++ Redistributables:

Download and install in order:

• Visual C++ 2015-2022 x64
• Visual C++ 2013 x64
• .NET Framework 4.8

GPU Driver Clean Installation:

1. Download Display Driver Uninstaller (DDU)
2. Boot into Safe Mode
3. Run DDU → Clean and restart
4. Install latest GPU drivers from manufacturer

5. Resource-Specific Crashes

If crashes occur only on specific servers:

-- Add to client.cfg in server-data folder
set sv_enforceGameBuild 2802
set adhesive_cdnKey ""

For servers with high resource count (>150):

-- Increase heap size in FiveM shortcut target
"%localappdata%\FiveM\FiveM.app\FiveM.exe" +set citizen_dir C:\FiveM\FiveM.app

• Windows 11 22H2+ may require specific compatibility settings not yet documented
• AMD FSR 3.0 implementations can cause instability with certain resource packs
