Password

You will need to enter a password as part of the installation process. The password you were issued after purchasing a Netica product contains 5 components:  your name, organization, product number, version number and a security number , in the following form:

   +Name/Organization/Product-Version-License/Security

The products will be either Netica Application (120), Netica API (310), GeoNetica™ (142) or a combination of the three.  The version number will be an integer, and your license will be one or more of: commercial (no entry), academic (A), site (S), etc. The numbers after the last backslash are a security code, unique to each license.

Here are some sample Netica license passwords:

   +MyName/ABCCorp/120,310-5/12345

    ^ version 5 license, enabling the GUI and the API.

   +Site/DEUniv/120-4-AS/54321

      ^ version 4 license, enabling an Academic site license of the Application.

This password is just to enable functionality in Netica.  It should not be confused with the password used to encrypt your Bayes net for security.  

Upgraded Passwords:  After upgrading your Netica license, you will be issued a new password. In most cases, you can simply download the latest version of Netica and input your new password.  However, if you already have the latest version and have been using a temporary password, or if you've recently purchased GeoNetica™, or Netica API and you received a new password, you can remove your old password by choosing File → Netica Password.

No Password:  When you run Netica, it will ask you for a password. You can either purchase Netica to gain full access to the software, or choose Limited Mode to use the free version.  Price list

Limitations of the free version:  In limited mode (i.e. used without a password), Netica is full featured, but doesn't work with large models.  For instance, it can't save a network having more than 15 nodes, and can't read one with more than 60 nodes.  Also, during learning, it can only learn from 1000 or fewer cases at a time.  There is a further limitation on the Netica API product - it can't build a net with more than 30 nodes, but that doesn't apply to Netica Application.
