How to update Hevacomp V8i to SP10


I'm trying to update our Hevacomp software to the latest version (currently V8i SS1 SP5). I found an older question ( where an engineer posted a link to this page - however that link is dead for me. ,

When I open the Hevacomp software and go to the configuration button I have no option to update.

Is someone able to point me in the right direction?

Thank you.
