W7 Update failure loop, error code 80070643
Hi
I presented this Windows Update problem, error code 80070643 to the forum about 18 months ago, and at that time I decided to reinstall W7 as it was the least complex option. The problem I have is a Windows Update failure loop which leads to the failure of all subsequent Windows Updates and also disables System Restore, and the update failure always starts with the .NET Framework update. When this problem started, it occurred every 6 months, so I had no major issues reinstalling just to correct it. Now it is occurring every 2 months, making re-installation unsustainable.
My question is this – Microsoft kb976982 states that an MSI fix, Microsoft Fixit 50123, should be used first to try to resolve the issue. When I tried to run it, I got the message
“Windows Installer – this action is only valid for products that are currently installed”.
Visiting Microsoft Help for more info about the Fixit50123, there was this System Tip -
“This article applies to a different version of Windows than the one you are using. Content in this article may not be relevant to you. Visit the Windows 7 Solutions Center”.
Even though there is an MSI.DLL file in W7 system 32, does that mean I do not need this Fixit50123 at all? If so, I can then go ahead and try the uninstall / reinstall the .NET Framework, secure in the knowledge that I did not miss one important step i.e. the MSI Fixit50123.
Thanks
