Hello, Magic Andre, thanks so much for your response. My OS is Winddows Vista Home Premium 32-bit. Here's what I've ascertained (as a computer novice) thus far. It appears that the nomenclature has evolved. What used to be identified as "x32" files, referring to 32-bit OS (rather than 64-bit) compatible files are now referred to as "x86" files (as opposed to "x64" files). This newer designation apparently refers to the "architecture", which I did see somewhere on my machine as "86" (and which I cannot relocate at this very moment). There is a UL with "x86" in the file name. At any rate, I managed to find individual download packages at the MS downloads website (Windows Update Standalone Packages). I have managed to individually install 4 of the 5 problematic updates. The final one, KB2631813, will not install after reboot. I have tried now 10 times (Windows6.0-KB2631813-x86.msu). The error code is: 80071AA7 I have found one remedy for this situation at: http://answers.microsoft.com/en-us/windows/forum/windows_other-windows_update/error-code-80071aa7/70a484f7-fca5-4d6b-baff-805160380a86?auth=1 However, this remedy involves actually inputting low-level commands and messing with the registry. I am not comfortable doing this. I do not have my CDs to reinstall Windows Vista. Is this update really that important? Any help suggestions greatly (!!!) appreciated. Cheers, Doug
