I'm in a bit of a bind. Before me is a Dell Dimension Windows Vista SP1 computer. Windows update has been failing when installing SP2. I researched the error and found about 4 possible solutions on the 'net. The first 3 solutions failed, including running the standalone installer, and the last is to perform what is called a Repair Install in XP lingo or what is more accurately called an In Place Upgrade in Vista language.
Okay, no problem, I can handle that. Except the OS DVD included with the system is just plain Vista with no Service Pack integrated and will only allow a clean install, not an upgrade. Not a good option really.
So I attempted to remove SP1 through Add/Remove Programs, and it failed with no specific error code. Then I attempted to run the SP KB installer from the command line with a switch to remove it, and that failed as well, with no error it just quit and SP1 was still installed after reboot.
Lastly I attempted to create a Vista install disk with SP1 slipstreamed and that has failed several times as well. There is conflicting information on the 'net as to whether or not it is even possible to slipstream Vista with SP1, but there are procedures out there, really just one procedure in numerous places, but it is not working for me, and may be due to the Dell OEM disk I have available or may be due to the fact that it is not possible period.
I need some suggestions, or it may be necessary to just give it up and mark it as not fixable short of a complete clean reinstall.
