I have installed R54 (secureplatform) from the CD, then upgraded to R55 (from file download) to get all my NIC recognised.
However, when I installed SmartConsole from the R54 CD, it does not work. First it does connect to the firewall and get the new certificate, then it fails saying "Connexion cannot be established, Incompatible version of Server"
I looked on Checkpoint web site for an upgrade of Smartconsole, but could not find any.
I even downloaded the version of the site, but it looks like it is the same as the other one.
You need to download NG AI R55 GUI client from Checkpoint. The filename is fwgui_541000127_2.exe. You can NOT use a R54 GUI client to connect to a R55 management server.
