How To: Installer troubleshooting (missing WebView2 required for Flow and Panorama)

Introduction

If you encounter errors when using Micromine Geobank starting from version 2023 SP2 (23.0.1266.2) to 2025 SP2 (25.0.1903.2) features such as Flow or Panorama, a missing or outdated WebView2 runtime may be the cause of this error.

Different versions of Microsoft Windows Workstations and Windows Servers may have different versions of WebView2 runtimes.

This article provides instructions on installing the WebView2 Evergreen Bootstrapper and offers additional troubleshooting steps.

Understanding WebView2

• WebView2 is a browser component required by certain Micromine Geobank features, including Flow and Panorama.
• Windows 11 includes WebView2 by default. Older Windows versions may require it to be installed.

Installing the WebView2 Evergreen Bootstrapper

1. To ensure support for WebView2, download and install the Evergreen Bootstrapper application from the link.
2. Run the installer with administrator privileges.
   
   
   
   
3. The Bootstrapper will download and install the correct WebView2 version for your system and keep it automatically updated. 
   If the installer fails, ensure you have administrator privileges on your machine.

Important Notes

• Installing WebView2 should not affect other applications on your system.
• The Evergreen Bootstrapper ensures you always have the latest WebView2 version (updates are typically released every 1-2 months) for optimal compatibility with Micromine Geobank.
