the WIS/ASRA I bought off ebay was being sold by mvkmimi1 @ $17. it worked
beautifully on my PC compliant desktop, i7 quad core 4790 on the first try.
I know of two other folks on MBworld and Benzworld who have purchased from
the same seller and they all reported success in installation and operation.

set up sounds similar to what you described (5 zipped files operating in virtual mode)
