Solution 26990: Version Number Error Using Catalog Help On The TI-84 Plus™ Family.
Why do I get a version number error when I try to use the Catalog Help application with the 2.53 or higher version of the TI-84 Plus Family Operating System?
If you are receiving an error message when trying to run Catalog Help on your TI-84 Plus Family Calculator, you should install the latest version of Catalog Help to your calculator. Catalog Help Version 1.1 is needed to run on operating system version 2.53 or higher, and Catalog Help 1.0 will give a "version number error" if you attempt to run it on the newer operating system.
