Update your video card driver

Many gaming problems are caused by damaged or outdated video card drivers. If your Rainbow Six Siege does not start, you can update your graphics card driver and restart the game to see if it works.

  • Go to the launch window by pressing Win + R. Then type in devmgmt.msc and click OK to enter DevMaster.
  • Double-click “Graphic Maps” to expand it.
  • Right-click the graphics card and select “Update driver”.
  • From the pop-up window, select Automatically check for updated drivers. Then follow the on-screen instructions to complete the process.

Temporary disable antivirus

Antivirus software is designed to protect your computer from cyber threats. However, sometimes it can block some game functions and cause problems. The problem with running Rainbow Six Siege may be due to interference from your antivirus software. You can temporarily turn off your antivirus to see if it will help you.

You can also add Siege to your antivirus software exception list. Please refer to your antivirus documentation for instructions if you don’t know how to do this.

Check game cache

If your graphics card driver is updated, but the problem is not fixed, you can try this method. This method checks the game files and checks if they are correct. What else, it will download and restore the necessary files. So the problem with running Rainbow Six Siege has not been solved.
Note. If you just update the drivers, you need to reboot your computer first.

  • Log out of Uplay and close it.
  • Run Steam. Right-click on the game and select Properties.
  • Select Local files and click Check game file integrity.
  • Run Rainbow Six, Uplay will open, and you will be prompted to bind your account.
  • Then your game will start automatically!

Reinstall the Microsoft Visual C++ distributed package.

If your headquarters and Uplay (including BattleEye) are installed successfully, but Rainbow Six Siege doesn’t start, you may need to check the supported software.

  • Type “Control Panel” in the search bar and press Enter.
  • Set up a view of the large icons and click “Programs and Components”.
  • Find the latest version of the Microsoft Visual C++ package you are distributing. Right-click it and select “Edit”.
  • Click Repair. Then follow the on-screen instructions.
  • Note. You probably have more than one installed. So try fixing them if necessary and reboot your computer when prompted.
  • Run the Rainbow Six Siege to verify this.
