Extract all files from the .zip file to a directory of your choice, e.g. c:\Program Files\iQgen. You can use any location you like, just make sure that you remember to replace your installation root directory wherever we refer to it throughout the documentation. In the root directory, you will find scripts called iqgen.bat (for Windows platforms) and iqgen.sh (for Unix or Cygwin installations). The file iqgen.bat assumes, that Java was correctly installed and java.exe is part of the %PATH% variable. For iqgen.sh, modify it and set JAVA_HOME to the appropriate value, e.g. c:\jdk1.3.1.
