Activation cannot occur if the serial number and product key combination is
invalid, or if the user is disconnected from the Internet. In such cases, the user
must contact Autodesk to resolve the situation. Some products provide
instructions for offline registration. This can involve generating a request
code, sending it to Autodesk, and then receiving an activation code to enter
on a product screen to complete the activation process.
If you upgrade your product from an earlier version, you may need to provide
your old serial number. For more information on activation, go to
Autodesk
Licensing and select the FAQ link.
NOTE If you are installing and using an Autodesk product on both operating
systems of a dual-boot operating system, you must obtain a separate activation
code for each operating system.
Registration
Depending on your product, registration is optional or required. If required,
you are prompted to create an Autodesk User ID associated with an individual
or company account. If registration is optional, you can choose to postpone
it, and you will be reminded periodically to register. The Autodesk website
where you register products is

Stand-Alone Licensing
Introduction to Stand-Alone Licenses
A stand-alone license authorizes a single user to use the specified Autodesk
product. The product can be installed on more than one computer, but
multiple instances of the same product cannot be running concurrently on
different computers.
Stand-alone licensing allows you to use your Autodesk product in trial mode
for a specified period, usually 30 days, from the first time you start the product.
For a product suite, the trial period countdown begins when the first product
is started, and it applies to all Autodesk products in the suite. You can activate
your license at any time before or after the trial period expires.
The licensing process creates a license file and a minor change to the
computer's file system. These changes remain on your computer when you
