Ever since I first started using Resolve with the last version of 16.x,
none of the versions have
ever installed a Start Menu entry for the actual application. I get entries for the RAW Player, the Speed Test, Control Panels and the Fairlight Studio Utility, but never for Resolve itself.
I've always downloaded the install kits from
the BlackMagic Support Page. I always use an unprivileged account and enter the admin password when the UAC prompt appears upon running the installation program.
So what I did was, after installing, go into the Resolve program folder at:
C:\Program Files\Blackmagic Design\DaVinci Resolve
...find the "Resolve.exe" file, right-drag it to the desktop and click on "Create Shortcuts Here". Then I right-click the shortcut and select "Pin to Start". Once the start menu shortcut is in place I delete the shortcut from the desktop to keep the desktop uncluttered.
