I wouldn't waste your time. I tried that and failed.
In the end I did a system restore to a time before I downloaded all of yesterday's patches - which removed ALL of them.
I them went back to the Windows Update site and downloaded/installed them all again EXCEPT for the offending KB917283. I've permanently 'hidden' that update until such time as MS work out why so many people are unable to install it
because I did a restore to yesterday, before I'd downloaded them, and when I went to the download site, intending to do as you had, I wqas told that the offending download was already downloaded, waiting to be installed... i.e. the system restore hadn't "deleted" the update file!
As a matter of interest, did you find out where the download file is stored?
