cant install updates!!

I'm able to rename edb.log to edb.old on my XP home. Why don't you try to rename the one in the bold and underlined? The information below is from Microsoft and appropriate links are listed below:

/Edit:

Updates fail to install and you receive error message 0x80070643

Problem Description:
When you try to install security\Critical Updates the installation fails and the Windows
Update.log file contains error 80070643.


Resolutions:
Suggestion 1
==========
This can occur if the hotfix installer was referencing:
C:\WINDOWS\system32\CatRoot2\edb.log and the file was corrupt. Either renaming C:
\WINDOWS\system32\CatRoot2\edb.log or renaming the entire
C:\WINDOWS\system32\CatRoot2 folder will allow the hotfix install to complete
normally.


Rename the Catroot2 folder
Rename the Catroot2 folder (Windows XP and Windows Server 2003 only), and then try to install the program again.

Note Skip this method if the operating system is Windows 2000.

To rename the Catroot2 folder, follow these steps:
1. Remove all tmp*.cat files from the following folders:
%systemroot%\system32\CatRoot\{127D0A1D-4EF2-11D1-8608-00C04FC295EE}

%systemroot%\system32\CatRoot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}

2. Click Start, click Run, type cmd, and then click OK.

3. At the command prompt, type the following commands, and then press ENTER after each line:

net stop cryptsvc
ren %systemroot%\System32\Catroot2 oldcatroot2
net start cryptsvc
exit

Suggestion 2
============
Register the following system files.

1. On the "Start" menu, click "Run."
2. Type "regsvr32 licdll.dll" (without quotes).
3. Click "OK."
4. Type "regsvr32 regwizc.dll"(without quotes).
5. Click "OK."

Suggestion 3
============
This can 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. On another computer that has the Microsoft Root Authority certificate installed, do the following:
1. Open Internet Explorer.
2. Click "Tools," then click "Internet options."
3. Click "Content," and then click "Certificates."
4. Click "Trusted Root Certification Authorities."
5. Scroll down until you locate Microsoft Root Authority certificate.
6. Click "Export."
7. Follow the prompts to export the certificate to "DER encoded Binary
x.509(.CER)" file. On the computer that cannot install updates, follow the steps to import the certificate you saved.

Suggestion 4
============
Try deleting the WUTEMP folder or removing the contents in that
folder. There might have been a trace of a past download or corrupted content
in the folder that is causing the download to fail.

Temporarily disable any virus and Web accelerator/enhancement programs.
