known reasons for this:
You're running Vista 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.
Google Update isn't registered
properly. To fix this, verify that
GoogleUpdate.exe exists in the
location specified in the Windows
Registry Editor.

downloaded successfully, but it failed
to install properly.
Try restarting your computer. Then
check your Windows Task Manager and
see if GoogleUpdate.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

help us investigate by reporting the
problem.
