Fix: VirtualBox only showing 32-bit and no 64-bit versions

This tutorial will show you step by step what to do when VirtualBox is only showing 32-bit and no 64-bit versions of operating systems as options while creating a new virtual machine.

Note: This may be obvious for most of you, but your host operating system should be 64-bit to run 64-bit guest operating systems in VirtualBox.

My experience with this problem

I experienced the same problem while trying to install a 64-bit version of Linux Mint inside VirtualBox.

I opened VirtualBox, clicked on NEW, entered a name for the virtual machine, choose the type of operating system, but when I wanted to choose a version, I only saw 32-bit versions and NO 64-bit versions as an option.


Fortunately, I found a simple solution online and on this page, I will share that solution with you.

Note! Your host operating system (OS installed on your PC) must be 64-bit.

I was using a 64-bit version of Microsoft Windows 10 Pro while creating this tutorial.

Solution 1: Repair VirtualBox installation

1. Right-click on the installer file (the one you used to install VirtualBox) and choose Run as administrator.

If you don't have the installer file anymore, then you will need to download it from the VirtualBox website ( The installer file must be the same version as the version of VirtualBox that's installed on your computer.

2. When the Windows User Account Control window appears, you click Yes.

Note: You might need to enter an administrator password in the User Account Control window and then click Yes.

A setup window will appear.

3. Click on Next.

4. Click on the Repair icon.
