This year we can download the software from the Subscription site, this makes receiving the software much quicker!
Just login to your subscription site (https://subscription.autodesk.com/ ) and select the Downloads button/link.
You may have already received an email about it, the email should contain your serial number and new product key. You need this to actually do the install. If you have not received an email from Autodesk yet, you can call the Autodesk Business Center (ABC) at 800-538-6401
Use this link to view the AutoCAD 2011 system requirements:
With AutoCAD 2010 I have started recommending 64-bit system. It may be time to upgrade if you have a 6+ yr old computer like mine. It runs the Network License Manager just fine though so I can't get rid of it yet.
Let the downloads begin!
