The first beta release of Analytica 4.5 and Engine” href=”” target=”_blank”>ADE is now available.  This kicks off the beta testing cycle for this next release of Analytica and ADE. To see a list of new enhancements, visit What’s New in Analytica 4.5?

Be a beta tester

We invite you to be a beta tester, and here is what we ask of you:

  • You should have an internet connection. Beta licenses are automatically activated over the internet and the software needs to check for new builds so it can alert you when new builds become available.
  • Sign up as a beta tester by filling out the User Info form in the installer.
  • During the beta testing period, always keep up-to-date with the latest beta build.
  • Report bugs that you encounter to us (  Include your model and steps required to reproduce problem with each bug report.
  • Have patience if problems arise during the beta cycle.
  • Start using the final release when the beta testing period ends.

As a beta tester, you can ensure that your existing models work flawlessly in the new release, and if there is a problem you can let us know while there is still time for us to fix it. That way, you will be confident that you and your model users will have no trouble transitioning to the new release. You can start using or just previewing the newest features. If you do find and report bugs to us, the next build is just around the corner, so you get fast turn-around.


If you are already an Analytica user with active support, the beta installer obtains a 4.5 beta license for your same edition (Professional, Enterprise or Optimizer). If you are using 64-bit Windows and have active support, you may install the 64-bit edition even if your former license was for 32-bit, and you will be able to continue using 64-bit when the 4.5 is officially released.

If you are not yet an Analytica user, or if you are an existing user but your support is not active, we invite you to beta test the Analytica Free 101 edition.  The Free 101 edition is new to the 4.5 release, and you may use it for educational, non-commercial and commercial uses. With the Analytica Free 101 edition, you can build your own models of up to 101 user objects.

Keeping Analytica 4.4 installed

You do not need to uninstall Analytica 4.4 when you install 4.5 beta. It is a good idea to keep them both installed, making it easy to go back if you need to, or to compare results in both.  When you double-click on a *.ana file to launch it, it will launch in the most recently installed version.

New features

The list of new features is at What’s New in Analytica 4.5? A few of the highlights are:

  • A new Analytica Free 101 edition. You can build your own models, up to 101 user objects, using the Professional edition features. As the name implies, this edition will be free, for academic, non-commercial and commercial use.
  • Same price for 32- and 64-bit editions. Automatic update to 64-bit license for existing users with active support.
  • Unicode support, multilingual sorting order and improved accent awareness.
  • Easy indentation while editing.
  • Parameter assist: shows possible values for enumerated parameters while editing an expression.
  • UI controls (choice pull-down  and check boxes) display in edit table cells while in edit mode.
  • Improved multidimensional data export and import.
  • Built-in logistic regression functions in all editions.
  • Support for complex numbers with relevant built-in functions.
  • Built-in Fast Fourier Transform function.
  • Built-in Negative Binomial and Wilcoxon distribution functions.

Models with Chinese content is enabled by new Unicode support in 4.5.

Backward compatibility

We place a high priority with every release to make sure that a new release is able to load and evaluate models from earlier releases. Analytica 4.5 is no exception. Models from Analytica 4.4 and earlier should work just fine when loaded into 4.5. If you find this not to be the case, we want to hear about it during the beta testing period.

While there are a couple of enhancements that have some possibility of impacting existing models (see Backward compatibility), we think there is a low risk of these impacting any given model that already runs in 4.4.

If you use unicode characters in your 4.5 models, these (and other extended characters) won’t be preserved if you then load the model into 4.4. If you don’t use non-ascii characters (i.e., if you stick to the characters formerly available in 4.4), you don’t need to worry about this. To learn more about this issue, see Model File Character Encoding.
