Strange things happening....
I have a bunch of RSLogix5000 V20 .ACD files that open perfectly well on my desktop PC, but when I try to open them on my laptop, they try to open with V21 (Logix Designer), and of course, fail to open.
This happens even if I have V20 running, and do a "File->Open", or if I double-click the .ACD file.
Has anyone seen this strange behaviour, and more importantly, know how to solve the dilemma ?
TIA
