Like I said above, Windows XP isn't supported anymore and hasn't been supported for at least a year if not more now.
If you're seriously still running Windows XP, I would *highly* suggest looking into upgrading to a newer Windows OS (at least Windows 8.1, since Windows 7 is going to die in a few months) or switching to a Linux distro or even just straight up replacing PCs running Windows XP. Running Windows XP on a PC that's connected to the internet is a
serious security risk, since Windows XP doesn't get security updates anymore. I really can't stress this enough, to stop using Windows XP in this day and age.
EDIT: Just tried the 32-bit version of Media Center 25.0.113 on an old Windows XP VM install, and as expected MC25's installer won't work as it will display the aforementioned error after MC25's installer is finished extracting. My best guess is the installer requires something in Windows 7 or newer at this point and time (which would make sense). Thus, I wouldn't expect MC25 to work on Windows XP anymore though.
Here's a screenshot of the error when running the 32-bit MC25 installer on Windows XP:
