Yes - Download the installer from our site and unlock it using the instructions (and license) found in your Image Line Image-Line Account.
IMPORTANT: If you purchased a Boxed version of our products, or an unlock code to redeem on our website, from an online or retail store you MUST register it to your Image-Line Account before you lose it. If you do lose your code, then there is no way for us to know you ever owned it. A receipt does not qualify as proof of ownership. Any product codes will be your responsibility until you register and redeem it here.
