After installation you can run the program by means of your 'Start' menu. (An uninstall facility is provided in case you wish to remove the program.)
- The file you download will be either the installation program (eph464_setup.exe) — as from this site — or a zip file (eph_setup.zip) containing it.
- If it is the zip file then double-click on the icon to run your default zip-file program to extract the installation program.
- Double-click on the icon for the installation program to install the trial version.
An activation key is required in order to make the trial version fully functional. An activation key can be obtained immediately upon your purchase or soon after.
