Google Chrome: Fix “Update server not available” Errors

"Update server not available"

In Google Chrome’s "About Google Chrome" box, you might see an error when trying to check for updates. Note the error message (or lack thereof) and click the corresponding link below to find out more:

Update server not available (error: 1)

Error 1 means that Google Chrome can’t be upgraded in its current directory.

First, check which version of Google Chrome you’re running by looking at the version number in the About Google Chrome box.

If the box lists "Google Chrome," then the most likely reason for this failure is that the Google Chrome files have been moved out of their default installation location. This configuration isn’t supported for updates. Moving the files back to their original location should resolve this issue. If you haven’t moved the files, you may be able to resolve this issue by uninstalling and reinstalling Google Chrome.

If the box lists something other than "Google Chrome" (e.g. "Chromium"), then this error is expected. Only Google Chrome supports updating. You can download Google Chrome from http://www.google.com/chrome

Chromium is what you get if you download the source code and build the browser yourself, or copy a build from someone who built it from the source.

Update server not available (error: 3)

Error 3 is a failure to communicate with Google Update. There are two known reasons for this:

1. You’re running Vista/ 7 and you have configured Google Chrome to always run as administrator. This is a known issue with the Google Chrome auto-updating mechanism and can be avoided by simply running Google Chrome as a normal user. Additionally, keep in mind that for security reasons we recommend that you don’t elevate the privilege of Google Chrome to administrator.
2. Google Update isn’t registered properly.

   To fix this, verify that GoogleUpdate.exe exists in the location specified in the Windows Registry Editor.

   The instructions below involve viewing your registry. If you’re uncomfortable or unfamiliar with this, you may want to consult your local computer guru before following these steps.

   1. Go to the Start menu > Run.
   2. Enter regedit.
   3. Click OK. The Registry Editor should appear.
   4. In the tree view on the left, navigate to the following directory:

      HKEY_CLASSES_ROOTCLSID{2F0E2680-9FF5-43C0-B76E-114A56E93598}LocalServer32

   5. The "Default" value should correspond to the location of your GoogleUpdate.exe or GoogleUpdateOnDemand.exe file. Verify that GoogleUpdate.exe exists at the given path.
      • If GoogleUpdate.exe doesn’t exist in this location, try uninstalling and reinstalling Google Chrome.
      • If GoogleUpdate.exe or GoogleUpdateOnDemand.exe exists at a different location, right-click the ‘Default’ value and select Modify. Enter the correct file path and make sure you use double-quotation marks, e.g. "C:Documents and Settings%USERNAME%Local SettingsApplication DataGoogleUpdateGoogleUpdate.exe(or GoogleUpdateOnDemand.exe)"
3. You can also try reinstalling Google Chrome and install through an alternate installer .

Update server not available (error:4)

If you’re still experiencing Error 4, please post the details in our help forum.

Update server not available (error: 7)

Error 7 means the update was downloaded successfully, but it failed to install properly.

Try restarting your computer. Then check your Windows Task Manager and see if GoogleUpdate.exe or GoogleUpdateOnDemand.exe appears in the list of processes. If it does, try updating again through the browser again. If you’re still encountering problems, try reinstalling Google Chrome from http://www.google.com/chrome

If that still doesn’t fix the problem, help us investigate by reporting the problem.

Checking for update never completes

If you see the message "Checking for updates" and a little icon that spins forever, it means that Google Update was unable to communicate with Google Chrome. Make sure that you are using the latest version of Google Chrome, available at http://www.google.com/chrome

I don’t see any error/status message of any kind

If you open the About box and don’t see any status message at the bottom (such as "Checking for updates"), it means that on-demand updates are disabled.

Make sure that you are using the latest version of Google Chrome, available at http://www.google.com/chrome

If you’re using Vista, also make sure that you have one of the following:

• Windows Vista SP1 (or higher) installed
• User Account Control (UAC) enabled
