Hola,

Method 1: Rename the Edb.log file
This issue may occur if the hotfix installer references the Edb.log file,
and the file is corrupted. To resolve this issue, rename the Edb.log file.
To do this, follow these steps: 1. Start Windows Explorer, and then open
the following folder:
C:\WINDOWS\system32\CatRoot2\
2. Right-click the Edb.log file, and then click Rename. Rename the
file "Edb.old."
3. Start Internet Explorer, and then open the Windows Update Web site
to continue the updates.
If you still cannot install the updates, rename the CatRoot2 folder. To do
this, follow these steps: 1. Start Windows Explorer, and then open the
following folder:
C:\WINDOWS\system32\
2. Right-click the CatRoot2 folder, and then click Rename. Rename the
CatRoot2 folder "CatRoot2old".
3. Start Internet Explorer, and then open the Windows Update Web site
to continue the updates.

message that the DllRegisterServer succeeded, click OK.

and then click OK. When you receive the message that the DllRegisterServer
succeeded, click OK.

Method 3: Repair the certificate
This issue may occur if the "Microsoft Root Authority" certificate or the
"NO LIABILITY ACCEPTED, (c)97 VeriSign, Inc." certificate under Trusted Root
Certification Authorities has been removed. To resolve this issue, follow
these steps: 1. On another computer where the Microsoft Root Authority
certificate has been installed, open Internet Explorer.

Encoded Binary x.509-format file (.cer file) file on a floppy disk or to a
shared folder that is accessible to the computer that cannot install
updates.
8. On the computer that cannot install updates, open Internet
Explorer.
9. Click Tools, and then click Internet Options.
10. Click the Content tab, and then click Certificates.
11. Click the Trusted Root Certification Authorities tab.
12. Click Import.

14. Click Browse to locate the file that you saved to a floppy disk
or to a shared folder, and then click Open.
15. Click Next, click Automatically select the certificate store
based on the type of certificate, click Next, and then click Finish.

Method 4: Delete the WUTemp files
This issue may occur if the contents of the WUTemp folder are corrupted. To
resolve this issue, delete the Windows Installer temporary files.

Note These files are stored in a hidden folder. You must make the folder
visible.

To delete the Windows Installer temporary files, follow these steps: 1.
Click Start, and then click My Computer.
2. On the Tools menu, click Folder Options.
3. Click the View tab.
4. Click to clear the Hide protected operating system files
(Recommended) check box.
5. Click the Show Hidden files and folders option, and then click OK.
6. Double-click Local Disk (C:).

Note If you have more than one hard disk drive on your computer, the
WUTemp folder may be located on another partition. For example, the folder
may be D:\WUTemp, or E:\WUTemp.
8. On the Edit menu, click Select All to select all the files in the
WUTemp folder.
9. On the File menu, click Delete. If you are prompted to confirm the
file deletion, click Yes.
If you still cannot install the updates, use the following method:
Method 5: Check the firewall, antivirus, and other software
A software firewall is a security system that acts as a protective boundary
between a network and the outside world. If you have a firewall installed,
it can prevent your computer from connecting to the Windows Update server.
Look in the notification area of your desktop (in the lower right corner of
your screen) to see if a firewall is running on your computer. In Windows
XP, you may have to show all icons in the notification area to reveal your
firewall icon. To identify the program that an icon represents, position
your pointer over the icon and wait several seconds. When you find the icon
for your firewall, right-click the icon. This action may reveal a menu that
allows you to temporarily disable the firewall. Some common software
firewalls include: ZoneAlarm, Norton Internet Security, McAfee Security, and
BlackICE.

To determine if the firewall is causing the issue, temporarily disable the
firewall, and then see if the error persists. If disabling the firewall
resolves the issue, contact the firewall software manufacturer for
directions about how to configure your firewall to allow you to use Windows
Update. Make sure that TCP/IP ports 80 and 443 are open in both directions.
Make sure that your firewall is not blocking scripting functions on Web
sites.

To determine if your antivirus or other software is causing the issue,
temporarily disable all non-Microsoft software, such as your antivirus
software, or any Web accelerator or Web enhancement programs, before
accessing the Windows Update Web site. If disabling the non-Microsoft
software resolves the issue, contact the software manufacturer for
directions about how to configure your software to allow you to use Windows
Update.
