One Time Installation Instructions

Lecture123 Installer for Windows

Download and run the Lecture123 Installer for Windows based computers. Click on the desired installer type below, save the file on your computer, and then run that program clicking through the various steps and screens that the Installer displays.

This installation is a two phase install: (1) run the installer, and (2) run Lecture123. Both phases require a network connection. Once the install is complete you must run either the Presenter or Player program the first time connected to a network so it can get any updates. This update action is performed automatically for you. However, if you install and try to run without a network the first time, you will get an error.

Lecture123 requires the free Java Runtime Environment (JRE) from Sun Microsystems.
The Lecture123 Windows Installer will install JRE version 1.5.0 (_10 or later; aka 5.0) if it's not already on your computer. If the JRE is being installed and the current Windows user does not have administrative rights, the Installer will warn you to run the Installer again as an admin user to complete the installation.
