What is BEX64?

BEX 64 is an error usually appears when File Explorer, a third-party app, or a game has crashed. This can be caused by conflicting processes or a problematic app on your PC.

Also, it can be due to activating some wrong settings on your PC. No matter the cause, we have a detailed solution to help you fix it in this guide.

How can I fix the BEX64 error?

1. Disable the amBX service

  • Press Windows key + R, type services.msc in the run box, and hit Enter.
  • Navigate through the list and Right-click on amBX
  • Choose Properties from the new menu.
  • Click the dropdown before Startup type and select Disabled.
  • Finally, click Apply to save the changes.

After you have passed through each of these steps, restart your computer. Launch the game, causing the BEX64 error after the startup is complete.

Some games, such as GTA V, will have issues with the amBX service. So, disabling the amBX feature should prevent the error.

2. Eliminate third-party interfering apps

2.1. Perform a clean boot

  • Press Windows + R, type msconfig, and click the OK button.
  • Click the Services tab at the top.
  • Check the box for Hide all Microsoft devices
  • Now, click the Disable All button.
  • Click the Startup tab at the top and select Open Task Manager.
  • Right-click each of the processes in the Startup tab and select Disable.
  • Now, go back to the Services tab and click the Apply button, followed by OK.

The clean boot will start up the system using only the Windows services loaded and the default programs necessary to function.

Using clean boot will also free up computer memory from your system and stop any process that can cause the BEX64 error.

  • Press Windows key + S and type cmd in the search box.
  • Click the Run as administrator option under Command Prompt.
  • Press Yes to grant admin access to User Account Control (UAC).
