It doesn't matter where you're from.
1. You have to purchase hauptwerk in the hauptwerk online store. They send you a dongle (usb) wich you need to use to activate HW.*
2. While the dongle is shipping, you can download the HW software and the HW usb key driver.
3. Also install HW before the dongle arrives.
4. When the dongle arrives, plug it in one of your usb ports, start HW and make a dongle update request file and send it to MDA. (see how to)
5. They send you back a file** with the updated dongle license, download it, start HW and aplly the new file.
how to*Mine was delivered in EU 3 days after the purchase.
**Can take longer than the stated 24 hours. Mine took about 2 days
So you don't get the key immediately, and you don't get it when the HW dongle arrives, you get it when you send the file.
