"The 80070643 error indicates problems with the .NET framework that will need to be repaired. http://support.microsoft.com/kb/KB976982"
This did fix the update problem on one computer. Still having issues with IE - but that seems to be a trend lately and firefox works fine. Thanks for your help with this one.
"The 80244016 error indicates the connection with Windows Update servers was disconnected, or the temp folder for Windows Updates on the PC is corrupted.
First place to start is here: http://windows.microsoft.com/en-US/windows7/Windows-Update-error-80244016-8024402f-or-c80003fa
If that doesn't work, the next step is to go into the services console (services.msc from the Start menu search bar), scroll down to Windows Update and doubleclick it. In the General tab, make sure startup type is set to Automatic or Manual. Then click the Start button to make sure it's started. Do the same for the Background Intelligent Transfer Service BITS. You may need to stop both services first, and then start them again.
If that doesn't fix it, then the temp folder may be corrupt. Close all running programs. Open the command prompt window as an administrator, type in net stop WuAuServ and hit enter. Go to Start search and type in %windir% . Look for the SoftwareDistribution folder and rename it SoftwareDistribution.old (the folder will recreate itself again once updates start working). In the command prompt windown, type in net start WuAuServ. You should get a message saying it successfully restarted."
Fix it ran but made minimal difference (some .net framework updates installed, other updates failed giving further errors of 80072EFE and 80072EE2)
Restarted both windows update and BITs from the service console - no such luck
Tried the third option - stopped Automatic windows update through the cmd prompt, but when attempting to change the filename to .old it would not allow me to do so, error: The folder or a file within it is in use by another program (I had closed all open programs)
As for the two new errors:
80072EE2 - ran fix it, seemed ok at first, but I am getting it again today
80072EFE - ran fix it - "could not find a problem", however, today I am not getting this error
Updates are still failing on the second computer, Flash still will not install.
As for the flash updates - I get the error "actionlist not found", when trying to install browser specific versions they fail as well.....
