ARES Commander is available in many different types of licenses including Perpetual, Annual (1 year), 3 Years, Network or Flex Cloud licenses: Compare the ARES Commander licenses.
The special offer "3 years for the price of 1" (with the 50% discount on the 3 Years Plan) is, by essence, only valid for our 3 Years Plan. But the price is so exceptional that it is more cost-effective than any other type of ARES license. After the 3 years license expires, you can easily switch to a Perpetual license or any other type of licenses provided. You will even remain free to return to your Perpetual license of CorelCAD if you wish. So, we invite you to see this offer as a trial for 3 years, before deciding which type of license you want to use after.
