Overwolf Installer

The Overwolf Installer is a generalized, fully featured, cleanly designed App installer, which you can easily use with any App hosted on the Overwolf Developers' Console, in order to deliver a seamless installation experience tailored just for your App.

When should the Overwolf Installer be used​

All Overwolf Platform Apps Always* use the Overwolf Installer.
This is done to ensure that no matter what happens, the Overwolf Client, as well as any other dependencies, are properly installed, and the App itself is properly installed on top of them all.

From there, every app can easily further customize its installer based on its own individual requirements.

* The Overwolf Installer is only displayed if Overwolf was not already installed on that computer. Otherwise, the app is silently installed as soon as the installer is executed.

Benefits of the Overwolf Installer​

Pre-flight Checkup​

One of the Overwolf Installer's main conveniences is that it takes care of many different things before/during installation for you, so that your app does not need to. Specifically:

  • (Overwolf Platform Only) Ensuring the installing computer is compatible with the Overwolf Client. For example:
    • The current OS version is supported by the App.
    • The computer has enough space to install the application.
    • The computer meets the minimum system requirements for the App.
  • Ensuring compliance with privacy regulations. For example:
    • Showing European users a fully fledged CMP Flow.
    • Ensuring that the user acknowledges and accepts Overwolf's ToS and Privacy Policy.
  • Allowing configuration of the target installation directory.
  • (Overwolf Platform Only) Allowing users to select between one of many supported languages, which then carry over to the actual installation.

Clean, customizable UI​

The Overwolf installer's UI is highly customizable. From the images displayed, to the options exposed to the users, all the way to the color scheme for different parts.

This ensures that your installer will always fit your App and your brand, without needing to create it all from scratch.

Decoupled from App/Client versions​

Ocassionally, updates may need to be performed for any installer, due to:

  • Changes in underlying installer dependencies
  • Various improvements to UX
  • Discovery of security flaws in installer dependencies
  • Issues with Anti-Viruses
  • Changes in minimum System requirements
  • And many more reasons

The Overwolf Installer is completely decoupled from the actual App it is installing. As such, if it ever needs to update, Overwolf takes care of it directly, without requiring any changes to Apps running it.

Minimal file size​

The Overwolf Installer does not actually contain the App's files when initially downloaded. Instead, it fetches the latest version during installation, ensuring that the initial download file for the user is kept as small and unintimidating as possible.
