Autodesk provides several Options for licensing their software. Which one makes sense for you depends on the situation you are in. There are four Options when you purchase the software:
Stand Alone: For individuals or small to medium businesses requiring a specific number of users. If you are a small office that has 6 people who will use the software and each one is full time, then this might be best for you.
Network: For medium to large organizations requiring many users. If you are a small, medium or large office with 6 or 10 or 100 plus people who will use the software mostly full time with some using it part time, this might be for you. You can have the part-timers share the license via a networked license server.
Students & Educators:
Students and faculty can download free* Autodesk software for personal educational purposes. Student licenses incorporate all the software functionality of our professional licenses, but include a print banner or watermark on output indicating the design was created using a Student license version. The stamp cannot be removed from prints and PDF’s. Autodesk Student licenses are available as Stand-Alone only and may not be used in the classroom or lab for instructional purposes, or for commercial or for-profit purposes.

Educational institutions, students and faculty can receive affordable pricing on a variety of Educational licensing options. Education Suites can be purchased as Stand-Alone, Multi-seat Stand-Alone or Network licenses and give academic institutions access to comprehensive software products and tools. Educational licenses cannot be used for commercial, professional or for-profit purposes.

Free Trial License: Try before you buy. The trial or “evaluation” licenses is available for most Autodesk products and allows you to download and run a fully functioning product for a period of up to 30 days. Again – not for commercial use. Many firms jump start the buying process by downloading a 30 day trial and then starting the purchase process so they can be up and running while approvals are processed.
Some things from the archives:
In 2006 I did a post on Autodesk Licensing Types . This covered Standalone and Networked license issues.
in 2009 I did two posts on the License Server options and my concerns about the fail safe it offered. It still appears that my questions have yet to be addressed.
