They way Euphony does updates to it's system is based on having two system partitions:
Update essentially downloads the whole system partition filesystem image and applies it to inactive partition. Once that is done system is simply told to boot from updated partition. Previously active partition becomes inactive one (and retains previous release to which you can always return to).
Important: when you burn euphony image to USB and boot from it you only have one system partition, the one you booted from. Inactive partition still does not exists.
To be able to receive updates you first have to register (Trial or full payed registration).
If you register for Trial and you want to receive updates during trial period you have to create this second, inactive partition. This is done by 'Complete installation' function. Complete installation will create this inactive partition from filesystem image that is already present in the filesystem of the image you burned to your USB.
When you register fully, you will now have 2 options:
Both of these options will work and behave in the same way if everything is alright. But in case of problems, Install option is much preferable.
Potential issues have to do with partition UUIDs. In Euphony we use UUID as main identifier for mounting partitions. Default system partition in Euphony image that you burn to USB has always the same UUID: d85fe591-2026-4e75-a314-44d5c435c372
If you run your Euphony from USB or other drive that you created by burning Euphony image to it you will always have that same UUID for your first system partition.
If something happens to your installation (corrupt filesystem or some other unforeseen error) and your system becomes inaccessible you usually have an option to boot from USB with fresh Euphony system image and run Install/Repair with your primary drive as destination. Install/Repair will preserve your music data and you can again have working Euphony installation with relative minimum fuss.
However, if you used Complete installation, your corrupt drive would have the same default UUID for it's system partition as the new USB drive you created for repair purpose. This will cause conflict, your system will behave unpredictably and you will not be able to do the Repair procedure. You will have to install everything from scratch, lose your music that you copied to Euphony Drive and all metadata. If you burned Euphony image to internal drive you may have to find a way to erase it completely (partition UUIDs must be deleted) to avoid that conflict so you can again boot Euphony from USB.
If you had used Install, newly created partitions would have got new UUIDs with no chance of UUID conflict and you would always be able restore Euphony on your internal disk by using USB drive with Euphony on it.
That is why Install is the best option.
