If you have an old .EDB file from 2009 sitting on a backup drive, 9.7.4 is still the key to opening it. Just don't try to design a 50-story buckling-restrained brace frame structure with it.
A Deep Dive into ETABS 9.7.4: The Forgotten Workhorse of Structural Analysis

For structural engineers who have been in the industry for over a decade, the version number 9.7.4 carries a certain weight. Before the ribbon interfaces, before the unified BIM workflows, and before the integrated concrete design modules became overly automated, there was ETABS 9.7.4. Released by Computers and Structures, Inc. (CSI) in the late 2000s, this version represents a pivotal moment in structural software history—a bridge between the DOS-era stability and the modern, graphically intensive nonlinear versions.
