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.
--------------------------------------------------------------------------------
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.
