Hello Mark,
I don't think it got fixed in Drone2Map 2023.1.
Installed by running MSIEXEC as follows:
msiexec.exe /i Drone2Map.msi CHECKFORUPDATESATSTARTUP=0 [...]
And checked the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Esri\Drone2Map\Settings\CheckForUpdatesAtStartup = 0.
But the 'About' screen still checks and says "Your Drone2Map version is current".
Maybe the next patch... or version...
. Luis
