Vista x64 Ultimate - Media Center missing??

I recently installed Vista Ultimate x64 (Upgrade), doing a clean install over
my previously existing Windows XP Pro installation (format). Several days
into playing with it, I've noticed that Media Center is nowhere to be found;
not through a search, nowhere in the start menu... nothing. I had assumed
that Media Center came with the Ultimate edition, but does it only come on
new PCs with TV tuning equipment....?

I tracked down the C:\windows\ehome directory and attempted to manually
start the ehshell.exe file, to which I receive this error:

"Windows cannot open this program because it has been prevented by a
software restriction policy. For more information contact your system
administrator."

When I ran the file, I was logged in as administrator.

I don't have a TV-tuner card.. I just wanted to run Media Center for
watching DVDs on my LCD. Let me know what further information you need to
help!

Just an FYI for Vista in general, logging in as Administrator does NOT run
programs as administrator.

If you right click, you should be able to "Run as administrator"

Doubt this is related to your problem, but it's worth mentioning.

I'd suggest trying the install again. If you've got an upgrade version,
don't install XP but do the following:

- format
- install Vista but do NOT put in your activation key
- once installed, do an upgrade install overtop of the existing Vista, using
your activation key.

Vista can use itself as an upgrade path.
