Unable to install SP1, error 800F0818

They were there and I had to replace them, which I did.

It says: Unavailable repair files:

servicing\packages\Package_for_KB2633879_RTM~31bf3856ad364e35~x86~~6.1.1.0.cat

So I assume theses files are NOT there(?)

They are really there. I updated the file again, here it is.

try to install Download Details Beveiligingsupdate voor Microsoft .NET Framework 3.5.1 in Windows 7 en Windows Server 2008 R2
Take this one Windows6.1-KB2633879-x86.msu 2.2MB it's for 32bits windows 7

this is english:
Download: Security Update for Microsoft .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 - Microsoft Download Center - Download Details

I will try to download and install this update now. Just a second.

By trying to install the last update I get the following error: Security Update for Windows (KB2633879).

EventViewer says: Installation Failure: Windows failed to install the following update with error 0x800f0818: Security Update for Windows (KB2633879).

I am able to install new updates (except SP1):
KB947821 successfull installed on 20-04-2012

Do you want me to uninstall that update?

And then install that one again?
