Hello Richard --
Your 2020 license had the link to V6 when it was production but V6 has since moved to the 'old pinpoint' place so you would have needed to ask us for this:
https://download.dc3.com/OlderPinPoi...6.1d-setup.msi
This should work fine for you on your new machine, though it has not been tested on Windows 11 (which didn't exist back when 6.1 was released)
The PinPoint 7 installer would have told you your license was expired and would not have let you install and thus render your PinPoint inoperative. We never force people to subscribe to keep their existing software running. But we prevent people from installing later versions with newer features only to find out that they are inoperable to license expiry.
