If an app on your PC just refused to launch with a message about WebView2 being missing, or an installer stopped halfway asking for the "WebView2 Runtime," this package is the fix.
Microsoft Edge WebView2 Runtime 149.0.4022.62 is the shared rendering engine that lets Windows applications display web-based interfaces - HTML, CSS, and JavaScript - inside what looks like a normal desktop program.
You install it once, and every app that needs it works.
What WebView2 Runtime Actually Does - in Plain Terms
Think of WebView2 as a copy of the Microsoft Edge engine that lives on your system purely for other apps to borrow.
When a developer builds a program whose interface is essentially a web page wrapped in a window, they have two choices: bundle their own browser engine - the way Spotify ships its own embedded Chromium copy inside every install - or simply call the system-wide WebView2 Runtime.
The second approach keeps each app dramatically smaller and means security patches arrive through one shared component instead of dozens of separate updates.
That is why so many programs depend on it today: Microsoft Teams, the new Outlook, Office add-ins, Windows 11 Widgets, and a steadily growing list of third-party utilities all draw their interface from this runtime.
In that sense it sits in the same family as the other invisible plumbing of Windows - DirectX for graphics and game rendering, or the Visual C++ Redistributable Runtimes for applications written in C++. You rarely think about any of them until something breaks.
Why Apps Suddenly Demand It - and What Breaks Without It
Windows 11 ships with WebView2 preinstalled, but Windows 10 historically did not, and aggressive "debloating" scripts or cleanup tools sometimes strip it out on either system.
When it is missing or corrupted, the symptoms are consistent: apps that open to a blank white window, installers that halt with "Microsoft Edge WebView2 Runtime is required to run this application," or background errors referencing msedgewebview2.exe.
The fix is the same in every case - install the official runtime from this page and relaunch the affected app.
No configuration, no restart in most cases, no per-app setup. If an app still shows a blank window afterward, a corrupted existing install is usually to blame; uninstall "Microsoft Edge WebView2 Runtime" from Windows Settings, then reinstall the fresh package.
Evergreen vs Fixed Version - Which One You're Getting
Microsoft distributes WebView2 in two flavors. The Evergreen build - the one offered here - installs once and then keeps itself current with the same regular Chromium platform and security updates that Microsoft Edge receives. This is what virtually all end users want.
The Fixed Version model exists for developers who need to lock their app to one exact Chromium build and package it themselves; if you are just trying to get a program running, ignore it.
Version 149.0.4022.62, updated June 10, 2026, supports Windows 10 and Windows 11 across x86, x64, and ARM64. Hundreds of apps share this one runtime, which is exactly the point - one download, system-wide coverage.
Before You Install: Quick Checks That Save Time
On Windows 11, check Settings > Apps > Installed apps and search for "WebView2" first - it is likely already there, and your problem may be a corrupted install rather than a missing one. On Windows 10, assume it is absent unless an app installed it for you previously.
The installer is safe to run over an existing copy; it simply updates it in place.
Note that WebView2 does not require Microsoft Edge the browser to be your default, or even used at all - the runtime is fully independent. If you have switched to an alternative like Zen Browser, WebView2 apps keep working exactly the same.
Get Microsoft Edge WebView2 Runtime 149 Free for Windows 11/10
The runtime is completely free, officially distributed by Microsoft, and carries no bundled extras.
Head to the Microsoft Edge WebView2 Runtime download page, run the installer, and relaunch whatever app sent you here. The whole process takes under two minutes on a typical connection.
Other Runtimes Worth Installing While You're Here
If a missing runtime broke one app, others are often missing too - especially on a fresh Windows install.
The Visual C++ Redistributable Runtimes All-in-One Repack covers the "VCRUNTIME140.dll not found" class of errors in one pass, and DirectX handles legacy d3dx9.dll complaints from older games.
On the media side, Media Foundation Codecs restores the decoders Microsoft stripped from Windows, while the HEVC Video Extension and HEIF Image Extensions fix iPhone video and photo playback specifically.
