Corrupted Microsoft Edge WebView2 installation

Why doesn't the app boot on Windows?

Modrinth App utilizes a specialized browser component that is native to the system it is running on. In the case of Windows, this component is the Microsoft Edge WebView2, which leverages the same technology that powers the Microsoft Edge browser.

💡 Microsoft Edge WebView2 is independent of the Microsoft Edge browser. Installing it doesn't install the browser and vice versa.

Many users confuse it with the actual browser and mistakenly remove its files, which, unfortunately, breaks Modrinth App. If you have made the same mistake, fear not — follow these simple steps to repair it:

  1. To get started, download the Microsoft Edge WebView2 installer and proceed with the installation.

  2. Once the installation is complete, give Modrinth App another go.

❗ If you encounter an “already installed” message, it's because you had Microsoft Edge WebView2 installed system wide. You must run the installer as administrator.
