Chapter 2
Installing LexiGuard



 

This chapter describes how to install LexiGuard from the installation CD and how to upgrade from a previous version of LexiGuard.

 System Requirements for LexiGuard

Hardware  IntelPentium with 64 MB of memory or Solaris Sparc station with 64 MB of memory
Software JavaRuntime Environment 1.2 (JRE 1.2) 
Java Cryptographic Extension 1.2 (JCE1.2)

The Java Runtime Environment 1.2 is needed in order to install and to run LexiGuard™. The LexiGuard™ installation CD contains a copy of the JRE 1.2. Alternatively, the JRE 1.2 can be downloaded from Sun's website at the URL http://java.sun.com

The Java Cryptographic Extension 1.2 is export-restricted. You must download it from Sun's website. They validate from your email address that you are located in the United States or Canada.


Installing LexiGuard from the CD

These  are the steps for installing the following software from the CD:
          JRE 1.2.2 (Java Runtime Environment)
          LexiGuard1.0
Note that if you already have JRE 1.2.2 installed on  your system, you can skip that step.

1. Make sure your system permits a sufficient number of environment variables to be
created.  We recommend that you set the environment size to a minimum of 2048.
There are a number of ways to do this. In Windows 95 or Windows NT 4.0 you can do the following:

       1. Open a DOS prompt window.
       2. Click on the Properties button in the toolbar.
       3. At the end of the Cmd line, add the text
                    '/e:2048'
           If this text line is already present, change the existing number to 2048 or greater.

2. Double-click on the My Computer icon and then double-click on the CD drive icon.  You will see two icons representing the contents of the LexiGuard installation CD.
One icon denotes the JRE 1.2.2 (Java Runtime Environment); the other icon denotes the LexiGuard package.

3. Determine whether you have a JRE 1.2.2 installed on your computer.  Type the command:
                    java -version

If your computer responds:

                   java version 1.2.2

then you have the correct version of the Java Runtime Environment needed to install and run LexiGuard; you do not have to install the JRE from the CD -- skip to step 3.

If you have an earlier version of the JRE or none at all, then you must install JRE 1.2.2 from the CD. To do this:

               Double-click on the JRE 1.2.2 folder icon
               Click on windows folder
               Click on the jre1_2_2-win-i.exe
               Follow the instructions in the install shield

3. Double-click on the CD icon.
Click on LexiGuard1.0 folder.
Click on Setup and follow the instructions displayed by InstallShield.

4. There are three modes of installation of LexiGuard:

Choose the appropriate mode radio button and click to continue.

5. After the software has been installed, you must reboot the system to effect the environment variable changes.

Note: If the system has trouble starting the program, click the operating system below
on which you installed software for steps to correct the problem.

      WinNT
      Win95/98
