Error code 800F0900 when installing Vista SP1
Hi all,
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.
Any suggestions?

It is 32bit Vista.
Already tried Vista SP1 standalone installer from Microsoft as stated in question and same error code appears while installing it as going the Windows Update route.

The 800F0900 error seems to come from a possible corruption in mmcico.dll. What I recommend doing is download the Vista SP1 from Microsoft, and simply run it that way, rather than using Windows Update. Get SP1 here:
