EasyBCD is a Windows application. It can only be run on a working Windows OS.
It is an application to manage the contents of the Vista/7/8 BCD.
It has no function on an XP-only system.
It will run on XP, but has no point unless that XP system is a part of a multiboot with Vista, W7 or W8. EasyBCD Basics - EasyBCD - NeoSmart Technologies Wiki
