Quick Note Before You Begin

Before trying any fixes, make sure of the following:

  • Your Windows 11 system is updated with the latest updates.
  • Your Mount and Blade game files are fully installed and not corrupted.
  • You have administrative rights on your computer (some fixes require this).
  • You have closed all other unnecessary programs to avoid conflicts.

Step 1: Restart Your Computer

Sometimes, a simple restart can clear temporary issues causing runtime errors. Restarting refreshes system resources and closes any conflicting programs running in the background.

How to do it: Click on the Start menu, select the power button, and choose “Restart”. After the computer reboots, try launching the game again.

Step 2: Run the Game as Administrator

Running the game with administrator privileges can help if the error is due to permission restrictions. This allows the game to access necessary files and system resources without being blocked.

How to do it:

  • Find the Mount and Blade shortcut or executable file.
  • Right-click it and select “Run as administrator”.
  • If this fixes the error, you can set it to always run as administrator by:
    • Right-click the file and select “Properties”.
    • Go to the “Compatibility” tab.
    • Check the box labeled “Run this program as an administrator”.
    • Click “Apply” and then “OK”.

Step 3: Update Your Graphics Drivers

Outdated or incompatible graphics drivers often cause runtime errors in games. Updating your drivers ensures your hardware works well with Windows 11 and the game.

How to update:

  • Press Windows + X and select “Device Manager”.
  • Expand the “Display adapters” section.
  • Right-click your graphics card and choose “Update driver”.
  • Select “Search automatically for updated driver software”.
  • Follow the prompts if a new driver is found.

You can also visit the graphics card manufacturer’s website (NVIDIA, AMD, or Intel) to download the latest drivers manually.

Step 4: Verify Game Files Integrity

If you installed Mount and Blade through a platform like Steam, corrupted or missing game files might cause runtime errors. Verifying the game files will check for and fix these issues.

How to verify on Steam:

  • Open Steam and go to your “Library”.
  • Right-click Mount and Blade and select “Properties”.
  • Go to the “Local Files” tab.
  • Click “Verify integrity of game files”.
  • Wait for Steam to finish the process and then try launching the game.

Step 5: Install or Repair Microsoft Visual C++ Redistributables

Mount and Blade requires certain Microsoft Visual C++ Redistributables to run correctly. Missing or corrupted redistributables often cause runtime errors.

How to fix:

  • Go to the Microsoft official download page for Visual C++ Redistributables.
  • Download the latest versions for both x64 and x86 architectures.
  • Run the installers and choose “Repair” if the option is available, or install fresh copies.
  • Restart your computer after the installation.

Step 6: Disable Antivirus or Firewall Temporarily

Sometimes antivirus software or Windows Firewall mistakenly blocks game files, causing runtime errors. Temporarily disabling them can help identify if they are the cause.

How to disable:

  • For antivirus: Open your antivirus program and look for an option to pause or disable protection temporarily.
  • For Windows Firewall: Go to Control Panel > System and Security > Windows Defender Firewall > Turn Windows Defender Firewall on or off.
  • Turn off the firewall for both private and public networks temporarily.

Important: Remember to turn your antivirus and firewall back on after testing to keep your system secure.

Step 7: Run the Game in Compatibility Mode

Windows 11 is new, and sometimes older games need to run in compatibility mode to function properly.

How to set compatibility mode:

  • Right-click the Mount and Blade executable or shortcut.
  • Select “Properties”.
  • Go to the “Compatibility” tab.
  • Check “Run this program in compatibility mode for:” and select “Windows 10” or “Windows 7”.
  • Click “Apply” and “OK”.
  • Try launching the game again.
