[ANSWERED] Run Winreducer 8.1 on Windows 8, 7, or Xp

hi.

i need to reduce a windows 8.1 iso, in order to burn it on a 4.7 gb DVD.

i belive i could do it, running, windows Reducer 8.1. (i have a 5.5 gb ISO of windows 8.1).

i have a laptop with windows 8, and a pc whit windows 7 and windows xp.

but, windows 8.1. (as the web saids) only can be run on windows 8.1, ¿is there any way to run it on windows 8, 7 or xp?

please help me.

Install Windows 8.1 on a virtual machine such as VMWare or VirtualBox and copy the ISO and Winreducer software to there and reduce from within the virtual machine.
Thats what I did.
