This guide will show you how to fix Windows’s Virtual Box installation error.

1. Run Virtual Box Installer As An Administrator

The User account control (UAC) determines whether the app should run in administrator or non-administrator mode. If the Installer is running the non-administrator mode, it won’t have enough privileges to write the temporary files it requires to install the Virtual Box; therefore, running the Virtual Box Installer as an administrator can grant the necessary permissions to the installer.

Follow these steps:

  1. Open the directory where your VirtualBox installer is located.
  2. Now, right-click on the installer, and click “Run as Administrator.”
