Download and install form•Z 6.7.3 Pro as described below.
If form·Z has not yet been installed on this computer / operating system, you will need to install the WIBU Runtime Kit, which you can download HERE.
(If you are using Windows, plug the key in after the WIBU Driver has been installed. If you have virus detection software, don't forget to disable this before installing, and if you are using Windows, you should check to make sure that you have a recent video driver.)
During the installation process, you will be prompted for your existing form•Z 6.7 installation code.
