Sometimes when Google Chrome is updated, an error prompt such as update server not available: error 3 (meaning "update service unavailable: error 3") will appear, and then the update will be terminated; After one occurrence, the same error will appear for each update. So how to solve it? Let me talk about the solution.
For this error, the Google browser update service is not registered in the application data folder of the windows system; If there is an update folder in the chrome directory, the problem will be solved as long as you register in this folder; In other cases, you need to uninstall and reinstall.
Solution to chrome Google browser error 3: 1. Select "start" menu → all programs → accessories → command prompt (win7 is best to right-click "command prompt" and select "run as administrator").
2. After opening the "command prompt" window, enter:
XP system: C: \ documents and settings \ current login user name \ local settings \ application data \ Google \ update\
Win7 and win8 systems: C: \ users \ current login user name \ appdata \ local \ Google \ update
Enter and enter Google update Exe / regserver enter, register the Google browser update service, and you can update it after success.
3. If you can't find the update folder update, you can only reinstall Google browser once. You can download the latest version and install it online.
4. If after the above operations, the update server not available: error 3 error message still appears in each update. It is best to uninstall it, download the latest version of chrome and reinstall it, or change to other browsers, such as ie, domestic browsers with IE kernel, Firefox and apple.
