Installing Sage 50 2020 Pro

SUGGESTED

I had Sage 50 2020 Pro installed...not the subscription.  I am downloaded a trail version of 2022 Premium and it seems to have taken over my exsisting program.  I have uninstalled the Premium trial version.  2020 Pro is listed as an installed program in my control panel.  But I can't access my files.  I have all the information, including the link for the 2020 Pro version.  The install link leads me to a knowledge base.

Can anyone guide me through acess to sage pro 2020?!
