@lohtse,
Number one if you have a purchased version of TopoActive Europe 2021.10 you do not need to unlock it with gimgunlock-up-v-0-04 or any other unlocker.
If there are problems with installing it to the Fenix 5x or the Oregon 650 then contact Garmin support for help.
You use Garmin Express to do the download and install.
