Link from ‘Check Now’ inside Rhino has this version: 8.8.24135.14001
I am a little confused regarding versions, but, my main issue is.
Do I need to uninstall and run installer again and download a 600MB file everytime?
Can I just run installer with my current version installed and it will update it?
There are two main ways to get the ~600MB installer file. The usual way for people with an online installation is to enable the Updates and Usage Statistics as you showed above. If you have chosen Service Release for the update frequency Rhino will background load the monthly Service Releases. If you have chosen Service Release Candidate the weekly SRC will be background downloaded.
