Cubase - Reason - windows XP


I install Cubase Elements 6 on windows XP computer. Cubase Element is supposed to have Rewire. I installed Reason Essentials 6 32Bits on the same computer.
But I don’t see any Rewire device available in Cubase devices menu.
I opened a 32bit version of Cubase Elements in Win7 and I got Rewire devices (Reason rewire, FL rewire, Sibelius rewire)
Why didn’t I get them in windowx XP?

looking forward to understanding where the bug is… :confused:
