There are a few reasons why the Oculus software is not installing;

What causes Oculus installation error

Reason 1. Antivirus is blocking the download

If you have an antivirus enabled on your PC, like McAfee, this software can prevent you from downloading applications that may come across as ‘malicious’ or harmful to your computer.

Reason 2. Windows software issue

The Oculus software is currently working on Windows 10. Windows 11 is currently not supported.

Your Windows software on your PC should also be updated to the latest version to ensure compatibility within.

Reason 3. Firewall enabled

If you have a firewall enabled on your computer, this will block the Oculus software from being downloaded onto your PC if it comes up coming from an untrusted network or site.

Reason 4. A headset is plugged in

Oculus users have reported that trying to install the software onto their PC while the headset is plugged in has caused problems with the installation.

Reason 5. Leftover Oculus files on your PC

If you have tried to install the Oculus software before and it has failed, there will be ‘leftover’ files on your PC that will be faulty and potentially interfere with the new install of Oculus.

Reason 6. Connected USB’s

Sometimes, unnecessary USB devices that are connected to your computer can interfere with the install process of the Oculus software.

(Did you know; you can use the ‘Fearless VR’ app to face your fears. the app will put you in a situation to help you overcome it, eg; a room full of spiders, or on top of a building).

Reason 7. Not enough disc space

If you keep having an Oculus error during the installation of the software, your PC may not have enough disc space to successfully load all the required data.

You need to have at least 9GB of free disc space for Oculus to install.
