Microsoft iSCSI initiator 2

Hello,

I am trying to install MS iSCSI initiator 2 to some Windows XP SP2 machines.
After downloading from MS site (Initiator-2.06-build3497-x86fre.exe), it
failed to install on OEM machines, coincidently. Is there any restriction
for iSCSI intitiator? Any how to acquire the proper software for OEM
licenses?

Thank you very much!
