Autodesk – Autodesk Revit Architecture Services & Support – How to download a previous release of an Autodesk Design & Creation Suite:

Scenario

You are an active Subscription Member and have upgraded to an Autodesk Design & Creation Suite, and would like to download a previous release of the Suite, or one of Autodesk software components within the Suite.

Solution

As a Subscription Member, you can download and activate the latest release, or previous releases, of eligible Autodesk products. You can activate one release of a product, suite, or the components of a suite, per license, purchased on Subscription.

Generally, if you purchased a license on Subscription for the first release of a Design & Creation Suite, then you can download and activate a previous release of the Autodesk software components within the Suite.

To download the product software for which you are eligible, follow the instructions for How to download a previous release of Autodesk software.

I recommended using Firefox with Downthemall to download these files. Finally, be sure to confirm the checksums / hashes before beginning the install.
EDIT:  Some people were having problems with these links.  However, this should no longer be a problem.
