right now, there seems to be no absolutely stable way to run Pleco on Windows, unfortunately. If you search for "arc welder" or "archon" in the forums, you can find reports from other users who have tried various Android emulators. The last reports aren't very encouraging, though. ("black screens")
On my android phone, I can display the app on my windows PC desktop. Would that be of interest? It's Dex for Samsung.
Also for android, there is a neat screen mirroring utility you can run to see your screen display on your desktop. I forget the name off the top of my head, but it could also be used for non Samsung android phones.
