Update will not install

[Rich Johnson]

When I try to use the Microsoft Update Web Site, some of
the Critical Updates download fine, but when it trys to
install, it fails.....

I have looked in the Knowledge Base and could not find a
usable fix.

Any help would be greatly appreciated!

If Updates fail to install:-



If you receive a 643 error message or a message indicating that Windows Update
was unable to complete the operation. This may occur if the catalog database
(Edb.log) is damaged.

Try this:- Click Start, click Run, type cmd, and then click OK.

At the command prompt, type the following command, and then press ENTER:

del /q "%SystemRoot%\System32\Catroot2\Edb.log

This command will force the catalog database to rebuild itself.

Errors Occur When You Try to Install Updates from the Windows Update Web Site



If the Windows Update scan feature reaches 100%, and then displays "There are
no updates available at this time" message.



Verify that your computer's date and time are accurate and that the Internet
Explorer language option is not empty.

To check the language setting in Internet Explorer:

1. Click "Tools" and then choose "Internet Options"

2. Click the "Languages" button

3. Make sure at least one language is listed in the "Language Options" dialog.

Windows Update Is Not Installed

http://support.microsoft.com/default.aspx?scid=kb;en-us;811269

This issue may occur if you use the AOL Web browser interface to access and
download Windows Updates. The AOL Web browser does not communicate properly
with the Windows Installer software, and this may cause Windows Installer to
stop responding.



You can download them from the Catalog and save to be installed later.

Hi Rich,

I am having similar problem. It downloads updates, but
will not install them. No error messages of any kind...
system just hangs up. Any advice?

Thanks.

Usually caused by a corrupt 'catroot2' file. To fix: Go to
C:/windows/system32 and locate the 'catroot2' file. Rename the file to
anything such as 'catrootold'. Reboot download and install. A new 'catroot2'
file will be generated.
