It's a full commercial version, but cannot be upgraded beyond 5.1.
Dongle and install discs 32/64bit included. Install instruction PDFs are also included, but I suggest you should be be proficient with the know-how needed for setting up a license server as there is no hand holding support.
It's an older version but it's still a powerhouse piece of software even for the compositing end alone...for someone who is willing to put up with not having the latest.
Here is a review if you forget what it had in it>
PM me if you are interested - to discuss cost.
