Why Diablo 4 won’t install?
Diablo 4 won’t install due to lack of disk space, poor specifications of your PC, compatibility issues with alpha or beta installation, Windows Firewall problems, outdated GPU driver, or problematic background apps causing compatibility issues.

How to fix Diablo 4 won’t install?

Perform these quick checks and fixes to ensure everything is suitable for Diablo 4 installation:

  • Check the disk space: If the start install button is greyed out, the lack of memory space is the most probable cause. Delete unnecessary files, apps, and games and try again after you have at least 50% available.
  • Check the system requirements: Diablo 4 system requirements align with the fact that it is a AAA game from 2023. Your PC must meet at least the minimum requirements for the game to install and run.
  • Uninstall the older version: If you played early releases of Diablo 4, uninstall them from your PC and restart it. Additionally, we recommend you delete the Diablo 4 folder from Documents.

Proceed with the step-by-step solutions listed below.

  1. Allow Battle.net through the Firewall
  2. Update the GPU driver
  3. Close background apps

1. Allow Battle.net through the Firewall

Windows Firewall might block the Battle.net while it is trying to install Diablo 4. Usually, the prompt will come up to ask you if you allow the app or not, but in case it doesn’t appear, you must add Battle.net as an exception manually.

  1. Click on the Windows icon, type Windows Defender Firewall, and open it.
  2. Click on Allow an app or feature through Windows Defender Firewall.

  6. Check the checkbox in columns Private and Public in the Battle.net row and hit OK.
  7. Restart your PC.

2. Update the GPU driver

Time needed: 5 minutes

An outdated GPU driver can cause various issues, including problems with Diablo 4 installation. To prevent this and gain performance boost once you end up playing the game, update your GPU driver.

  1. Click on the Windows icon, type Device Manager, and open it.
