Installation Troubleshooting:
- Heroes of the Storm requires an up-to-date operating system in order to run. Check for updates before continuing.
- The installer needs administrator permission to update the files on your computer. Be sure to use an administrator account.
- You must have a stable internet connection to install the game. If you experience connectivity issues, try optimizing your internet connection.
- If your game disk is damaged, or if you experience issues while trying to install from a disk, download and run the game installer from our site.
- Programs running in the background on your computer can interfere with installation. Close any running background applications and try again.
- Security software can interfere with our streaming installer. Try disabling or temporarily uninstalling your security applications.
- The Battle.net Update Agent helper program is what handles installation and patching for Blizzard games. Issues can arise if it is not functioning properly. Try troubleshooting Agent.

- Damaged, corrupt, or unreadable computer memory may cause installation issues. Run a Memory Diagnostic scan to check for memory issues.
- Malicious programs may interfere with the installation process. Run a security scan to find and resolve any infections.
