Installing Ungoogled-Chromium with ChrLauncher on Windows 11

Installing Ungoogled-Chromium on Windows 11 requires using ChrLauncher to manage the browser's isolated environment. This guide details how to download the launcher, configure the binary path, and resolve common startup errors. By following these steps, you can run a privacy-focused browser without Google services while maintaining compatibility with your existing Windows 11 system.

Understanding ChrLauncher and Ungoogled-Chromium

Ungoogled-Chromium is a project that strips out all Google-specific code from the open-source Chromium browser. It provides a browsing experience similar to Chrome but without telemetry, background services, or integration with Google accounts. Because it lacks the standard installation mechanisms found in regular Chrome, managing updates and execution can be tricky for average users. ChrLauncher serves as a bridge between the operating system and this specialized build. It allows you to launch the browser directly from its extracted folder without needing administrative privileges or complex registry edits. This tool is particularly useful on Windows 11, where security settings like SmartScreen and Controlled Folder Access might block direct execution of unsigned binaries. Using ChrLauncher ensures that the browser runs with the correct environment variables and permissions, preventing crashes caused by missing dependencies.

Prerequisites and Downloads

Before beginning the installation, ensure you have the latest version of Windows 11 installed. You will need to download two main components: the Ungoogled-Chromium binary and the ChrLauncher utility.

• Ungoogled-Chromium Binary: Visit the official GitHub releases page for Ungoogled-Chromium. Download the latest Windows x64 release. Choose the zip file rather than the installer, as this gives you full control over the directory structure.
• ChrLauncher: Obtain the latest release of ChrLauncher from its official repository. This executable handles the launching process and manages configuration files.

Extract both archives to a permanent location on your drive, such as C:\Browsers\Ungoogled. Avoid storing them in temporary folders like Downloads, as this can lead to permission issues when updating the browser later.

Configuring ChrLauncher

Once you have the files ready, the next step is to link ChrLauncher to the Ungoogled-Chromium executable. Open the folder containing ChrLauncher and locate the configuration file, typically named config.json or a similar settings file depending on the version. Open this file in a text editor like Notepad. You will see a field designated for the browser executable path. Enter the full absolute path to the chrome.exe file inside your Ungoogled-Chromium folder. For example, if you extracted the browser to C:\Browsers\Ungoogled\chrome-win64, the path should look like C:\Browsers\Ungoogled\chrome-win64\chrome.exe. Save the configuration file. Now, double-click the ChrLauncher executable. If configured correctly, Ungoogled-Chromium should launch immediately. If you encounter an error stating that the executable was not found, verify that the path contains no spaces or special characters that might break the command line parsing.

Resolving Common Startup Errors

Users often face specific hurdles when running Ungoogled-Chromium on modern Windows versions. The most frequent issue involves Windows Defender or SmartScreen flagging the browser as potentially unwanted software. Since Ungoogled-Chromium is not signed by a major certificate authority, Windows may block it by default. To resolve this, right-click the chrome.exe file, select Properties, and check the box that says "Always allow this app to run." Alternatively, you can add the entire browser folder to the exclusion list in Windows Security > Virus & threat protection > Manage settings. Another common problem is the browser failing to create local storage directories. This usually happens if the user account does not have write permissions to the installation folder. Ensure that your current Windows user has Full Control permissions for the C:\Browsers\Ungoogled directory. If you are part of a managed organization, you might also face restrictions on creating new profiles, similar to issues described in related articles about profile creation failures.

Updating the Browser Safely

Unlike standard browsers that update themselves silently, Ungoogled-Chromium requires manual intervention for updates. To update, download the new zip archive from the GitHub releases page. Extract the contents into the same folder, overwriting the old files. It is crucial to back up your User Data folder before overwriting, as this contains your bookmarks, history, and extensions. After extracting the new version, simply relaunch the browser via ChrLauncher. The launcher will detect the new executable and apply the updated configuration automatically.

Additionally, if you experience unexpected behavior with extensions or analytics tracking, reviewing guides on Disabling AdBlockers in Chrome: Accessing Google Analytics can provide context on how Ungoogled-Chromium handles third-party scripts differently.

Frequently Asked Questions

Can I sync my Google account with Ungoogled-Chromium?

No, Ungoogled-Chromium explicitly removes all Google service integrations, including account synchronization. You must manually export and import your bookmarks and passwords using HTML files or password managers. This isolation is intentional to prevent any data leakage to Google servers.

Is ChrLauncher safe to use on Windows 11?

Yes, ChrLauncher is an open-source utility designed specifically to manage unofficial Chromium builds. It does not collect personal data and runs locally on your machine. However, always download it from the official GitHub repository to avoid modified versions that could contain malware.

Why does Ungoogled-Chromium crash on startup?

Crashes are often caused by permission issues or corrupted user data. Check your Windows Event Viewer for detailed error logs. Ensuring your user account has write access to the installation folder and clearing the Local State file in the User Data directory can often resolve these stability issues.

How do I install extensions in Ungoogled-Chromium?

You can install extensions by downloading the .crx file and dragging it into the chrome://extensions page. Since the browser lacks the Chrome Web Store integration, you must enable Developer Mode to sideload extensions manually. Be cautious of extensions that attempt to re-introduce Google services.

Does Ungoogled-Chromium support hardware acceleration?

Yes, hardware acceleration is supported and enabled by default. If you experience graphical glitches, you can disable it by navigating to Settings > System and turning off "Use hardware acceleration when available." Restarting the browser is required for changes to take effect.
