To begin the upgrade, run the CitectSCADAv7.20 installer. The installer will lead you through a number of steps until the installation is complete.
Note: Uninstall any existing version 6.x or version 7.0 before installing v7.20, as CitectSCADA does not support different versions running side-by-side. Additionally, to use the v7.20 Example and CSV_Example projects, it is recommended that you delete the existing Example and CSV_Example projects using Citect Explorer before starting the installation.
