Got the WIS/EPC installed. It uses "Virtual Box" as a driving engine for the program. Comes with good, clear installation instructions. Had a few glitches installing
VB, probably my fault.
I put it on my desk top machine, haven't tried it on my laptop. Seems to require an internet connection but I won't know for sure until I install it on my laptop. I do know it doesn't like my wireless Epson XP-600 printer but that's nothing new. I've got an old HP inkjet I can use if I need print-outs.
The EPC covers about every manifestation of Daimler Benz since 1962 or so. I haven't had any reason to delve too deeply into its depths, yet.
The WIS covers from about 1985 up.
Well worth the $20 and a couple of hours of installation time it required.
