Install the component

System requirements

Item	Requirement
OS	Windows 10/11 (64-bit)
foobar2000	v2.0 or later (64-bit)
WebView2 Runtime	Usually preinstalled on Windows 10/11; otherwise download it from Microsoft

Note

foobar2000 v2.0 is the 64-bit cutoff. If you still run v1.x, upgrade to v2.0+ first.

Install the component package

1. Download the package: get foo_ui_webview2-<version>.fb2k-component from the release page; <version> is the component version.
2. Install it through foobar2000: open or double-click the package so foobar2000 shows its component install confirmation.
3. Confirm: click Yes and let foobar2000 install the package contents.
4. Restart foobar2000.
5. Select the UI: File → Preferences → Display → Default User Interface → choose Webview2 UI.

INFO

.fb2k-component is the official foobar2000 component package format. Install it with foobar2000's component installer; do not treat the package as a plain zip that you unpack by hand into the profile.

To use the component as a panel inside Default UI or Columns UI instead of as the whole interface, skip step 5 and follow Put a page in a panel.

Manual binary install (not recommended)

Release packages contain architecture-specific binaries (foo_ui_webview2.dll, WebView2Loader.dll, and an x64/ layout). Copying only a single DLL into an arbitrary components folder is incomplete and layout-dependent. Manual extraction is only for advanced recovery.

Verify the installation

After a successful install you should see:

• The Default User Interface list includes Webview2 UI
• Menu entry View → WebView2 UI → Show/Hide Window
• Preferences page File → Preferences → Display → WebView2 UI
• Advanced branch File → Preferences → Advanced → Tools → WebView2 UI

The component installs no theme. Until a template holds an index.html, the main window shows a built-in test page whose buttons try out the API, and a panel shows "Frontend not found. Please install a template."; Install a theme and Build your first theme cover getting one.
