    John, none of this is a very good advertisement for Cadence. Everyone who needs your viewer is a potential new customer, and this is a big problem for all of us, and embarrassing for Cadence, that your shiny new viewer can't read any old files, which are being shared with us by your current customers! Bad for all. I too, need to use 16.6, it seems, to open the board files shared by Microchip for their Polarfire boards. Your 1GB (!) download won't open it, bombing that I need the old version. Your links below lead to a place that forces us to register, and then loops endlessly either asking for our info again and again, or download the latest. Can you please, please post the old versions in an obvious place (e.g., <support><downloads><old versions>) so everybody can get productive again? Thanks in advance!
