I'm getting error code 800F0900 when installing Vista SP1 using the standalone installer.
When I try to install using Windows Update it will not download (stays at 0%) and eventually times out with the same error code above.
One suggestion I found said to try installing the Windows Update readiness tool (KB947821) first. I tried installing this but it stalls while installing the update.
Another suggestion I found on the net said to do an inplace upgrade. I want to avoid this especially since this is an HP system with no Vista CD so I don't even know how to do an inplace upgrade. Also don't want to re-install the Apps.
