provides step-by-step instructions about how to install AutoCAD on your system. You should read the entire Stand-Alone Installation Guide if you have any questions that are not addressed in this Quick Start section. For information about installing network-licensed or multi-seat stand-alone versions of the program, see the Network Administrator's Guide.

Before you install AutoCAD, you need to review the system requirements, understand administrative permission requirements, locate your AutoCAD 2009 serial number, and close all running applications. After you complete these tasks, you can install AutoCAD.

Some Autodesk packages are comprised of multiple products or are part of multi-product bundles.

You can export your custom settings between systems running the same release of AutoCAD, or export the custom settings and later re-import them on the same computer if you need to reinstall AutoCAD. When exporting custom settings, a migration package is created that contains an XML file. This file contains custom settings, a listing of the custom files from local locations used with AutoCAD, and optionally, custom files in network locations.
