Thanks for the replies so far. The seller says the version of software they have is 'ColorGenius EX for FT-S5500 Version 2.0.1 Client/Server package' At first I thought this was fine - but know I'm wondering about the 'client/server' bit. I noticed that the ColorgeniusEX server is listed as an optional extra in the Elite brochure (where as plain colorgeniusEX is standard). Does anyone know if this client/server package will actually be the software to run the scanner or is it just software to enable the scanner to be run on more than one machine (whilst still requiring the original EX software)?
