It sets up some standard variables and starts transcript so any errors are caught and can be viewed. If installations are taking place via MSIEXEC, it also establishes the log file. If you are installing more than one installation, make sure you setup multiple Install_Log variables for each installation and name the end of the log file accordingly It starts transcript to the transcript log file so the history can be accessed anytime in the future The script then tests for the CT_DEST folder and creates it if its not there.
