EFS support on XP Home Edition

We are

developing a special protection to some applications, and we need to support

Windows XP Pro, XP Home andVista. We

found that this API is supported on XP Pro andVista (http://www.microsoft.com/technet/prodtechnol/winxppro/deploy/cryptfs.mspx).

Does anyone know if is possible to install it on XP Home or if it's now available

installing some new Pack, like SP2?
