After you register your PIN, you will receive an email from Autodesk. This email confirms that your subscription has started. Autodesk recommends that you begin using your product only after you receive this email. Once you have received it, you will only need your Autodesk ID and password to use the product on any computer. A serial number will not be necessary to use the product.
Why does the AutoDesk product ask me for a serial number?
