Original post here. Was told to post in this forum.

Both KB2971850 and KB3000850 fail.

Running Windows 8.1 Enterprise 64 bit.

Steps tried:

 - Log on as Administrator

 - Stop Windows Update Service and clear SoftwareDistribution\Download and DataStore.

 - Perform clean boot by disabling all startup and all non-MS services

 - Download and run WindowsUpdateDiagnostic.diagcab

 - Download standalone installers for each KB update

Absolutely nothing works. Looks like other people have had the same error however one of the above steps always seemed to fix it.

Can anyone help?

1. Update readiness tool

2. Being logged as administrator is NOT enough, you should run scripts/cmd with elevated/priviledged rights (Run as Administrator)

3. Use Process Monitor to do detailed analysis and post your results in Sysinternals forum.

Hi Gardnerp2,

You can follow these steps to troubleshoot this kind of issue:

You can't install updates in Windows Vista, Windows 7, Windows Server 2008, or Windows Server 2008 R2

1. There's no update readiness tool for Windows 8.1 - at least that I can find. That's meant for people updating from Windows 7.

2. Tried that - CMD as Administrator, used WUSA and same result.

If anyone else is having this issue, Alex's link did solve it. From the steps in his link:

I had already done steps 1, 2, 8, and 9 so I did not redo them. Meanwhile steps 3 and 6 were not applicable to Windows 8.1. I did complete steps 4, 5, 7, and 10. After this it worked. Not sure which one was the specific fix. So I did not ever get to steps 11, 12, or 13.
