Hello,
If you buy the stand alone version Start11 it's a one time purchase for that version and all future updates,
Good for 1 PC activation. or upgrade that for 5 PC activations
Just The 30 days trial version has the 30 days support all others full time support .
If a newer version become available there would be a upgrade price to upgrade to the newer version.
If you buy Start11 as part of the Object Desktop package with other apps included then that is a yearly
subscription but that includes any new versions for no extra charge . and 5 PC activations .
