How to Troubleshoot Hardware Access Error in Facebook Messenger

If your Windows 10 has hardware support for features like a camera and microphone, you can make video calls on Skype, record videos, and more. Many third-party apps, such as Facebook Messenger and other services, require access to the camera or microphone to enable their special features. However, sometimes you get an error message on your screen when you try to video chat with a friend on Facebook:

An error has occurred while attempting to access the camera and/or microphone: Hardware Access Error.

Facebook then deliberately tries to direct the customer to a support page and offers some basic troubleshooting tips, such as making sure no other applications are running in the background, checking the Internet connection, restarting the browser and computer, etc.

What causes ‘Hardware Access Error’ in Facebook Messenger?

  • This problem is mostly due to incompatible permissions and browser or outdated Windows/system drivers. This problem can also be caused by conflicting devices, drivers, or applications.
  • Outdated Windows and system drivers are the root cause of many system problems. If an outdated version of Windows or system driver is not compatible with Facebook, it can cause your current hardware to be inaccessible.
  • A Facebook hardware problem can be caused by a bug in your browser. Every browser stores settings and temporary memories along with installation files. If any of these files are corrupt or incomplete, you will have problems like those mentioned here.
  • Windows has its own library of built-in drivers. A hardware error can occur if any of the necessary devices, such as the camera and microphone, use a third-party or outdated driver.
  • If any of the Facebook browser/website resources are unavailable due to a third-party application, Facebook triggers a hardware access error. The third-party application will run in parallel with your browser.
