If you visit http://www.autodesk.com/inventor, you will see a Free Trial link.
When some of you click on it, you will see an option to try Inventor nline.
I say "some of you" instead of "all of you," because the Autodesk web site runs a quick test to determine if your internet bandwidth is sufficient to run Autodesk Inventor using an application remoting solution. In this case, the application remoting solution is provided by our hosting partner.
For those of you where this option is available, you download and install a 7MB remote client that allows you to connect to the remoting service. The 7MB download/install is a much quicker way to get going with Inventor as compared to the full 1GB Inventor download/install. In addition this approach allows you to try Autodesk Inventor 2011 without having to do side by side installs next to earlier versions.
You only have to install the remote client once. In fact it's easy to take Inventor 2011 for several test drives as the install process leaves a shortcut on your desktop for subsequent uses:
I created a somewhat raw YouTube video that shows how this worked on my new HP EliteBook 8540w computer I got today (Monday, 8/23 when I wrote this and recorded the video). This machine doesn't have any Autodesk software on it yet.
