Unable to install update for KB938371 with error code 80070020

Original title: Error 80070020 with KB938371

 

I keep getting this same error code 80070020 with the single update KB938371


Every other update has installed fine but this one just fails every time.

I have used the MS Fix It tool to reset Windows Update and I've tried things like deleting the SoftwareDistribution folder but with no joy.

Please help?

Thank you for your reply. No joy I'm afraid:

Method 1 - same problem

Method 2 - not applicable

Method 3 - successful download, but installed reports "Update does not apply to your system". Yet this update still appears in Windows Update as a requirement.
