KB2732487 is unable to update - Error Code 800700B7

OK - now run another SFC /SCANNOW and post the new CBS.log file.

As far as I can see, there's no problem with the report.

What error do you get (if any) if you simply run a Check for Updates?

It seems the only reliable cure for this problem (at least that I've found) is a repair install of the OS - most instances appear to be caused by problems with the Windows Update Agent, but those whould show up in the CHeckSUR report, I think.

I really can only recommend a repair install at this point.

Download the SP1 Refresh for your language and edition from the links on these pages...

Heidoc - Microsoft DR Download links

The links are for downloads from the Digital River servers run for MS, so are about as safe as you can get :)

Once you have it downloaded, you then need to burn the DVD from it - use either the Windows Disk Image Burner, or (better still) your favourite burning application at the slowest speed possible.

Note that you do NOT 'drag and drop' the file to the disk, you must use the 'burn an image' option from your app - or you'll end up with a useless coaster :)

Once you have the disk burnt, check that it boots the (or any other) system OK - but do NOT start the repair from there - you must start the repair from within a normal Windows boot.

Follow the instructions in this tutorial - https://www.sevenforums.com/tutorials/3413-repair-install.html
- and they should help you get through it (it's not as difficult as it looks!)


Good luck with it!
