📁 3. Clear Ubisoft Connect Cache

Sometimes corrupt cache files cause this error.

Steps:

1. Close Ubisoft Connect completely (check Task Manager too).

2. Press Windows + R → type %ProgramData%/Ubisoft → press Enter.

3. Delete the Ubisoft Game Launcher folder (or rename it to something like Ubisoft Game Launcher.old).

4. Relaunch Ubisoft Connect — it will rebuild the cache.

🧩 4. Install/Repair Required Dependencies

Ubisoft Connect needs specific components to run. These include:

🔹 Visual C++ Redistributables

Install (or repair) both:

• Visual C++ 2015–2022 Redistributable (x64)

• Visual C++ 2015–2022 Redistributable (x86)

🔹 .NET Framework

Make sure .NET Framework is up to date:

• Download .NET Framework 4.8 Runtime

🔥 5. Disable Conflicting Apps (Overlays, Antivirus, etc.)

• Turn off overlays (e.g., Discord, MSI Afterburner, Rivatuner, GeForce Experience).

• Temporarily disable your antivirus/firewall and try launching again.

• If Ubisoft Connect works after this, add it to your antivirus “allow list.”

💾 6. Check for Windows Updates and GPU Drivers

Outdated drivers or OS files can cause crashes.

• Run Windows Update.

• Update GPU drivers from:

  • NVIDIA

  • AMD

  • Intel

🔍 7. Look at the Ubisoft Connect crash logs

1. Go to: C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\logs

2. Open the latest .log file with Notepad.

3. Look for any lines showing the crash cause (e.g., DirectX error, missing DLL, etc.).

If you’re stuck, you can paste that log section here — I can help interpret it.

💡 Optional: Try launching the game directly

If a specific game causes the crash:

• Go to the game’s folder (e.g., in C:\Program Files (x86)\Ubisoft\games\)

• Try launching the .exe file directly.
