App Does not Install on Newer Devices (e.g. Vivoactive 6)

[jones139]

Users have reported that the app does not install on some of the newer watches, in particular Vivoactive 6.

The symptoms are that you copy GarminSD.prg into /GARMIN/APPS and when you disconnect the watch from the computer you see the 'Verifying Apps' screen, but then GarminSD is not listed as an app and is no longer in the /GARMIN/APPS folder. There are no error messages on the watch.

Building V2.0.7 using the latest SDK (V8.2.2) results in an executable that runs on the Vivoactive 6....but then the older ForeRunner 245 shows the issue - GarminSD is deleted from /GARMIN/APPS and it is not listed in the possible apps.

Is it possible to build an executable that works on both old and new watches?

Another user has reported this problem affecting a Vivoactive 5 device too.
GarminSD_v2.0.7x.prg in the V2.0.7 release (https://github.com/OpenSeizureDetector/Garmin_SD/releases/tag/v2.0.7) is built with the latest SDK (V8.2.2) and has solved the issue for the users of the Vivoactive 5 and Vivoactive 6.

BUT GarmiNSD_v2.0.7x.prg does not install on my older watch, so the release now contains both versions for users to try.
