my pc finally died so i need to reinstall BIAB. I bought the ultrapack in 2018 so i'm tempted to install BIAB 2018, activate it and leave the download manager to do the work of installing the vast number of RealTracks. Then add all my bonuses, xtra styles and upgrades to 2021 manually.

i'll delete the installers and downloads once i'm up to date. am i right in thinking that i don't need to activate or even open the various upgrades as i go along until i finally get to 2021 and then if i install the latest BIAB and RB patches they are cumulative and will include all the RealTrack fixes since 2018?
