Cannot install program Windows Mobile Device Center

I am running Vista 32 bit. I downloaded from MS the Windows Mobile Device Center installation file. When I run the install, the progress bar gets down to the very end, says 0 secs left, then it sits there for about 15 seconds and then the progress bar goes backward and all the install dialogs go away with no message. And the program is not installed. When I rebooted the screen is blank, Vista does not boot fully.

I restored the computer from an image I had made previously with Norton Ghost. I downloaded a new copy of WMDC and ran the install, it did the same thing.

Any ideas?

Thanks

I was avoiding restarting the computer for fear it would give a blank screen again, but I did restart it and it seems ok, so it did not corrupt Vista like before.

But I do not see WMDC in the Start menu. Now I am wondering if it is not supposed to show up since WMDC is just a driver, (I think) not really an application. Maybe it will start automatically when I plug in the phone, which is not here right now, my wife returns with it later.
