need to run BYE2.0 on WindowsXP machine; not accepting my license

[Norm]

Hi. I have purchased the Premium version, BYE3.1 or .2 and use it, or have been, on a Windows10 machine. While I still use a Canon DSLR, my main imaging train is now a QHY168c controlled by NINA. I do not wish to run BYE on two systems simultaneously and will not but I would like to use another telescope/mount/camera /computer system as well, using an old laptop that runs WindowsXP. I downloaded and installed BYE 2.0.9.23794   When I try to validate my license, I can't. Suggestions?

Not possible.  BYE 2.0.9 was released in 2012. This activation server is no longer active and there is no way for me to create new keys from that older activation server.

You purchased in 2017, and you can only go back to 3.1.0 with your key.

Try 3.1.0 2014-12-16, it was tested on XP back then.

Thanks! seems to do the trick. Hope you all have a healthy and happy new year.
