Windows XP Media Center edition is only available as an OEM version,
which is intended to be sold either preinstalled on a new computer
system, or as part of a package of components for a person who is
going to assemble their own computer.
Because it is an OEM version it is specifically designed not to
install as an upgrade over an existing version of Windows. So you
cannot just install it as an upgrade/overlay of your existing XP Pro.
You might repeat might be able to do a Repair Install of the XP Pro
using the XP Media Center edition CD as per the instructions at
http://michaelstevenstech.com/XPrepairinstall.htm but I am almost
certain that this will fail because of the version difference. Having
never tried it, however, I cannot say this for certain.
Your options at this point would appear to be:
1. Return the XP Media Center edition and exchange it for a copy of
XP Pro. Then do a Repair Install per the above link.
or
2. Use the Files and Settings Transfer Wizard from the Media Center
CD to save your data files and configuration settings to another hard
drive partition, a removable backup device or a network drive. Next
reformat the hard drive and install the Media Center edition and
reinstall all your application programs. Then run FASTW again to
import the saved data.
Good luck
