I have used Rhino 6 in the past with a license I had on a separate computer. After my old computer broke from water damage (I no longer have access to it), I purchased a new computer with the intent to download rhino 6 again on it. While I still have access to the previous rhino 6 license, I see no option for me to download rhino 6 onto my old computer, and would rather not have to purchase a new license to use rhino 7, when the upgrades in the software don’t particularly impact the material that I am working on. Is there any way to download Rhino 6?
You can download it here:

You can use your previous license key - you may need to contact sales@mcneel.com to get the validation released if your old computer failed before you uninstalled the license key.
