Can't seem to get any answers...i see a 64 bit download. Is that for windows 8? if there is a W8 compatible version does it work with touch screen? I want to buy a windows tablet but there is no app for windows 8.1 RT and i don't even see a download for windows 8.1 (full version). Does anyone out there know anything about eDrawing use on windows 8.1RT or full version windows? Please tell me i don't have to buy an iPad!
