I have the demo version of ARC 500 and I just successfully loaded my new Pro-197 after a few tries. (Reading the directions several times helped!) I have seen the screen shots for WIN500 and I like the layout of it better. Does anyone have experience with both software packages that can give me an honest review of which one they liked the best? I have the seven day demo period and have subscribed to RR so I will be doing a lot of learning over the next few days. I am an experienced scanner user as well as adept with a PC. Thanks for honest opinions as I know a purchase of a package must be made. I would like to make sure I get the one best suited for my abilities.
