The Microsoft Edge WebView2 offline installer is an indispensable tool for developers, IT administrators, and anyone who needs to deploy modern Windows applications in environments without reliable internet access. Understanding the distinction between the Evergreen Bootstrapper (online-only) and the Evergreen Standalone Installer (true offline) is the most critical takeaway from this guide.
When the bootstrapper (the ~2 MB online installer) is used in an unattended scenario, the command is:
: Even if you pre-deploy the runtime, include it in your application installer as a fallback. This covers edge cases where a specific machine might have missed the pre-deployment or where an older version needs to be updated. Embed the offline installer and run it with the /silent /install parameters when necessary.
Locate the or the Fixed Version section. Select your architecture: x86 (32-bit Windows) x64 (64-bit Windows) ARM64 (Windows on ARM) Click Download and accept the license terms. Silent and Enterprise Deployment Commands
It installs completely offline. However, once the machine reconnects to the internet, it will automatically update itself via Microsoft Edge Update.
Download the installer once and distribute it across thousands of local endpoints.
For developers and IT professionals, performing installations without user interaction is often a requirement. The WebView2 offline installer supports this through command-line arguments.
MicrosoftEdgeWebView2RuntimeInstallerX64.exe /quiet /install /peruser=0
是微软推荐给大多数开发者的方案。在此模式下，WebView2 Runtime 不随应用一起打包，而是通过在线引导程序（bootstrapper）或离线安装程序（standalone installer）首次安装到客户端，之后 WebView2 Runtime 会在客户端上自动更新。它的优势在于：基础 Web 平台自动更新，开发者无需额外维护；客户端上所有 WebView2 应用共享同一个运行时，磁盘占用更少；在符合条件的系统上，Edge 浏览器和 Evergreen WebView2 运行时的二进制文件在同一版本时会硬链接在一起，带来磁盘、内存和性能上的优势。
