I doubt Rockwell will 'fix' v.16 for Windows 7/Vista, so a general rule of thumb, if you want all the prior revs is to use Windows 7 sparingly, and use virtual XP mode for the nagging versions. Or just stick with XP.
I'm sticking with XP for now. I have projects in 17.1 and 18.1 so I guess I'm lucky when corporate rolls out 7 on all machines in Q1. So far, I'm on the resist-list, as I have FTStudio and Logix500 as well.
