Because we have already Win8 clients in our environment i had to try this Patch on my WSUS 3.0 SP2 (which is a SCCM 2007 R3 WSUS).
Being careful i installed and tested it first on my lab machine which is a 2003 R2 server. No problem, the installation worked and i am now able to patch Win8 clients.
After some days of testing i applied the patch on the real environment which is a dedicated 2003 R2 server for the Software update role (WSUS) and Asset Intelligence component for the SCCM 2007 R3.
There the installation failed. I have enclosed a snipplet out of the log:
MSI (s) (38:04) [17:24:53:185]: Assembly Error:Der Prozess kann nicht auf die Datei zugreifen, da sie von einem anderen Prozess verwendet wird.

A clean rollback of the patch was not successful. So the WSUS was out of order. Fortunately i was able to fix this by myself. My hope is that i get some help in aspect of this installation issue? I hope the german log is okay for you.
