I am able to find the most recent version of Prognosis (11.4) here https://community.ir.com/t5/Prognosis-Installers/Prognosis-11-4/ba-p/55
Is this the same as Prognosis web session recorder? If not, where can I find the most recent version of that?
Prognosis and Prognosis Web Session Recorder are two Applications. The Web Session Recorder will be installed during normal installation of Prognosis. We always use Windows Server as OS and if you check installed Programs you will see that this are two applicatons. Also in Start-Program Files you will see a additional entry for the Web session Recorder.
I don´t know if it´s possible to install only Web Session Recorder but i expect not.
WSR/WSE hasn't been changed in a while, so if you already had a copy of WSR/WSE, you most likely have the latest.
