Hi Alex,
When you purchase SQL Anywhere, you receive a registration key that you must enter during the installation the product. That will license the database server according to what you purchased. Note that this registration key will be for production use (not development).
Once the database server is installed and you are ready to deploy, you can copy the appropriate files to your production server. The list of files to deploy is here:

Alternatively, you can just re-run the install program in your production server and simply provide your registration key at install.
