The "Trial Version" of NTpage requires that you obtain a NTpage license file.  This file is called NTPAGE.LIC and you will receive it via E-mail.  When you order your license file, you will need to know the computer name of the system that NTpage will be installed on.  The computer name can be found by clicking Settings/Control Panel/Network.  Once you receive the NTPAGE.LIC file, copy it into the \WINNT\SYSTEM32 directory.  This should be done BEFORE you run the NTpage installation program.
