This has by far been the most problematic service pack install I have ever done. First I tried through Windows Update and received an error. Rebooted the computer and then opened Windows Update once more. Clicked to check for updates to ensure I wasn't missing anything else and the only update that showed up was SP1. Tried once more to install and it failed. Downloaded the .exe from Microsoft's website and when I run it, I am informed that a component is missing.
Checked the prior posts in this thread and ran the automount enable option through partdisk. Tried to install once more from the downloaded .exe file but again received an error. Within the error I clicked to be directed to Microsoft's online help and they suggested running Windows install from CD within Windows and choose to check for all updates, then run the upgrade. Ran setup.exe from my ISO image of Windows 7 and chose all the options provided by the help file. Had to reboot because files were in use and then run the upgrade once more from the Windows desktop. At this point things started looking up as it seemed I was making progress with the component upgrade but then my connection to my home machine dropped (remoted in from work). Maybe I'm just venting and when I get home the process will have finished successfully and I can then install SP1 but even if that's not the case, this is such a PITA!
I always run Windows updates and my copy of Windows is legit so it just really bugs me
