You can not upgrade the WinIPDS (G52) with the WinIPDS Pro/Lite (G59) software. An already installed WinIPDS will not be affected by an installation of WinIPDS Pro/Lite on the same machine. The two products can run simultaneously.
A license key for WinIPDS can be installed into WinIPDS Lite and activate the same feature set. If you are using WinIPDS it is recommended to consider switching over to WinIPDS Lite as WinIPDS is discontinued and all future enhancements and bug fixes will be released for WinIPDS Lite only.
