Scroll down in the Software Update column to DaVinci Resolve Studio 16.2.8 Update (25 Nov 2020).
Note that the Studio installer is listed below the standard (free) version's installer.
Thank you so much. I saw that before, but I thought "update" means it's only an update and an earlier version is required before applying the update.. Now I realize it's in fact the full version and not an update.
