Welcome to the Microsoft Windows Vista Communities site.

Windwos Update Error 0x80070641

The definition of the error code you’ve received 0x80070641 can be found below:

ERROR_INSTALL_SERVICE_FAILURE - The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed.

If you can successfully install applications that rely on the Windows Installer then the service itself is most likely functional, and was simply in use at the time of the update. Thus, you will want to make sure that the Windows Installer service is not in use prior to attempting updates.

If the issue persists after you’ve confirmed no installations are taking place proceed with the troubleshooting below.

How-to stop the Windows Installer service.

If you are sure no installations or configurations, which rely on the Windows Installer, prior to updating you can try manually stopping the Windows Installer service, and then attempting Windows Update. If the error code persists after that the issue may be related to a corrupt or otherwise damaged Windows Installer.

Stop the Windows Installer service and then use Windows Update…
1. <br>Click<br>Start, click All Programs, click Accessories, right-click Command Prompt, and select Run as Administrator.<br><br><br>2. <br>At the<br>Command Prompt window type the following, and press Enter:<br><br><br>3. <br>net stop msiserver<br><br><br><br><br>	Note:<br>This will effectively stop the Windows Installer* service. This service will load-on-demand so manually stopping it does not adversely affect the computer.*	<br>	---	<br><br><br><br>4. <br>Launch<br>Windows Update, and then attempt to install the previously failed updates.

If this troubleshooting does not address your present error code please let the community know. Be sure to include all relevant information, and the steps you’ve already taken to try resolving this issue. Please include the results of the troubleshooting I’ve provided, and we would be more than happy to assist you further.

I followed the steps. 8 different updates still fail to sucessfully download:

1. Office 2003 SP3

2. Update Outlook 2003 junk email filter

3. Microsoft.Net Framework 1.1. SP1 security update

4. Microsoft.net Framework 3.5 SP1 security update

5. Security update Microsoft Visual C++ 2005 SP1

6. Security update Microsoft Works 9

7. Definition Update Windows Defender

8. Update Office 203

I'm running Vista 32 bit Home Premium.. Windows Defender is listed as an empty application in control panel. I cannot download windows defender and I get "The Windows Installer Service could not be accessed . . ." I cannot install Adobe Acrobat 9 Professional. I've tried turning on the RPC (which seems to work) and the Windows Installer (which will not start automatically) and the error message is the "path invalid".

Hi Dougerock,

This error means the following

"The windows Installer Service could not be accessed.this can occure if you are runninf windows in safe mode, or if the windows installer is not correctly installed."

Re-install latest windows installer..or you can try following command in command prompt..

MSIEXEC /Unregister

MSIEXEc /Regserver
