All right, I finally took someone else's advice and did a repair installation of Windows 7, and afterwards SP1 installed fine.  I have the Windows 7 Home Premium upgrade from Vista DVD, and selected "Upgrade" from the main menu.  All of my existing programs and data remained on the computer--my main reluctance with doing the repair install was the fear of losing my data and the hassle of having to back everything up and then restore, so that ended up being a non-issue.  So for all of you out there, give it a try--can't guarantee it'll work for you, but it did for me.

And to the Microsoft support team--couldn't any of you have posted this possible solution?  Seems pretty elementary.  All I've seen from support members is the suggestion to install after performing a clean boot, which doesn't work for many of the people on these forums.

Same Same Same here.....It will not install despite myriads of troubleshooting and I also have a lot of GB free on this partition...

Folks, I believe I have an answer to the problem. After trying many different options suggested above without success, I managed to install the service pack. As mentioned in a number of previous messages, the system partition is  the root of all evil. The system partition (this is not the partition that has win7 installed) is either too small or is full. You need a minimum of 20M or more for the install to work. My system partition was 100M in size and had only 5M free, this caused the service pack install to fail with the messages indicated above. On freeing up space (20M availability) the install worked successfully. To access the system partition (has no assigned drive letter) you need to use the win7 partition manager software found in the control panel, assign a drive letter to system partition, access the new partition, move a larger enough file from one of the directories onto a win7 partition, freeing up space, run the service pack install, installation should succeed. After rebooting from service pack install , reverse the process, copy file back to system partition and remove the assigned drive letter. All complete ............hope this helps!!!!!

Thanks for trying to help, but your advice doesn't work for me.  Using the partition manager, I can find no separate system partition; it just lists my main drive as the primary partition with the system on it, along with all of my other programs and data.  I have dozens of GB free on this partition, so diskspace shouldn't be an issue.
