Key notes

  • Running an operating system inside another can be done with virtualization software such as VirtualBox, which is free to download and use.
  • If you are having trouble installing it, there are three easy steps to make it run safely.
  • When this happens, one of the most typical problems is that the antivirus prevents the software from operating correctly.

VirtualBox fatal error during installation is often menacing for people hoping to use the virtualization application. This error will suddenly terminate the installation, and you will not be able to run Windows 10 as a host.

While installing VirtualBox is straightforward, you may sometimes face this difficulty. So we will navigate through triggers and solutions to the installation error.

Why is VirtualBox not installing?

From user feedback, we gather that various elements may be responsible for VirtualBox not installing on your computer. A few of these include the following.

  • Insufficient system requirements – VirtualBox requires a 64-bit CPU and operating system and enough free disk space and memory to function correctly. If your computer does not meet these requirements, VirtualBox may not install.
  • Antivirus software interference – Antivirus software can sometimes interfere with the installation process of VirtualBox. 
  • Conflicting software – Other virtualization software, such as VMware or Hyper-V, can conflict with VirtualBox and prevent it from installing. 
  • Lack of administrative privileges – If you don’t have the necessary administrative privileges to install software on your computer, VirtualBox may not install correctly.
  • Error messages – If you receive an error message during installation, take note of the error code and search for a solution online. The error message can help identify the specific problem preventing VirtualBox from installing.
  • Outdated drivers or software – VirtualBox may not install or function properly if your drivers or software are outdated. 
  • Corrupted installer – If the VirtualBox installer file is corrupted or incomplete, it may not install correctly. 

With these triggers out of the way, let us discuss some fixes.
