e/pop Web Conferencing (version 4.6) and Nefsis are almost identical in how they install. The primary difference is that with version 4.6 if you could not install the ActiveX control, you could download a small (1.6mb) iesetup.exe, which would in turn download and install the actual conferencing client. This hid the download and installation details of the 10.3mb setup.exe that installed the conferencing client. This was not an attempt at deception mind you, but an effort to give the user multiple methods of getting into a conference so that they would be able to participate.Nefsis has some fundamental changes to it that preclude the use of the iesetup.exe application. For this reason if users are unable to install the ActiveX control they may click on the link to download the CCsetup.exe manually. Once this is downloaded and installed, the user can launch the conferencing client from an icon created on their desktop. The client will then prompt them for the conference ID they wish to join and any applicable password. The Nefsis method of joining a conference is also beneficial in that it helps the user get around Windows vista's Protected Mode/UAC features that would limit the functionality of e/pop Web Conferencing.
