Error 0x800b0100 when installing KB2727528 and/or KB2761217

That's OK - I meant to remove that refernce, and forgot!

Not yet - I think I know what the problem is (I need to rename the files first, and I got one wrong anyhow)
Please delete the current packages.zip file, and the packages folder, while I work out what to do.

(thank god for Virtual machines - it makes things a lot less uncertain!)

I've posted a new packages.zip file

I've uploaded a file - packages.zip - to my SkyDrive at https://skydrive.live.com/#cid=936736BB8FCEB92F&id=936736BB8FCEB92F%21526
Please download and save it.
Right-click on the downloaded file, and select Extract all…
Extract to the default location - which will create a new folder packages in the same place.
Open this folder -
Copy the content of the Packages folder to the
C:\Windows\Temp\CheckSur\Servicing\Packages

Now run the CheckSUR tool again (it may take a while)

Post the new CheckSUR.log file, and the CheckSUR.persist.log file.


Then do a manual scan for updates and see what happens.

If you happen to be in the area sometime, you can always buy me a pint or three :)

Good luck!

Please, help me if you can. I have an error with .net 3.5.1 component (unable to enable-disable component, unable to install kb2756921)

results in attached sfcreport, sfcreport2 files

You've committed a cardinal error, I'm afraid - thread hijack!
