Hi: Can you go back up , I've edited my first comment, added stuff. I thought the main diff, btwn. Win 7 & Win 8 was basically the amount of memory it can handle ?
**bleep**, I have to go, I'll pick-up on this tomorrow. Seems to me, I'm screwed with this Win 8.1, though, in the AutoCAD 2013, it's the one asking for this .hnf file ??????????????
