Error Code 80070643

Question

Windows Update stopped functioning for me. Says I need an Update to get Updates, but the Update won't install.  Keep getting Error 80070643. Tried many things including installing windowsupdateagent30-86.exe/wuforce which won't install either.

Hello John,

I'm not sure whether you have attempted to recover your system or not because of issues with Windows Update. You might be able to try a system restore and see if you can get back to before you were having problems with Windows Update.

The error code 80070643 is a generic error that basically state that an error was encountered by Windows Installer.

Mark was correct in stating that you seem to have more problems than just with Windows Update.

However, you might want to look at the following KB article to see if this will help with the Error 80070643.

If you receive Windows Update error 80070643 while installing updates for Microsoft Office , you might need to restart the Office Source Engine (OSE) service. Windows Update can automatically start the service to install updates for Office products if the service is set to the default Manual setting. If the service is disabled, you need to restart it, and then try to install the latest updates for Office products again.

To restart the Office Source Engine (OSE) service
	You must be logged on as an administrator to perform these steps.	<br>	---	<br>	1.	Open Administrative Tools by clicking the<br>Start button , clicking Control Panel, clicking System and Maintenance, and then clicking<br>Administrative Tools.	<br>	2.	Double-click Services.  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.	<br>	3.	If the Office Source Engine service is disabled, double-click it to open the service properties.	<br>	4.	Click the Startup type list, click<br>Automatic (Delayed Start), and then click Apply.	<br>	5.	Under Service status, click<br>Start.

If the service fails to start, your OSE.EXE system file may be corrupt. You should run SFC and try again.

1.Click Start, and then type cmd in the Start Search box.

2. Right-click cmd in the Programs list, and then click Run as administrator.

3.If you are prompted for an administrator password or confirmation, type your password or click Continue

4.At the command prompt, type the following line, and then press ENTER: sfc /scannow

I ran the command.  Result was that it found some corrupt files it was "unable to fix," and referenced the file to the CBS log in Windows.  I could not access that file : "Access Denied"

You can search for [SR] tags to help locate SFC.exe program entries. To perform this kind of search and to redirect the results to a text file, follow these steps:

1. Click Start , type cmd in the Start/ Search box, right-click cmd in the Programs list, and then click Run as administrator.

If you are prompted for an administrator password or for a confirmation, type your password, or click Continue. 2. Type the following command, and then press ENTER: 3. findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >sfcdetails.txt

Open sfcdetails.txt in Notepad

After I enter that command and hit enter, nothing happens; just a blinking cursor at the beginning of the next line down.  Am I supposed to do something after I hit enter to bring up notepad here at the blinking cursor?
