Hi there,
I see now :-)
Well, it should work,-the only reason I can see as to why the client will not work is because it is installed on a system that it does not recognise as being a genuine Samsung screen or it is not integrated properly somehow.
There have been a few people on here who have wanted to install the client on another pc instead of an actual screen and discovered the client wont open.
Probably the best bet at this stage is to check with Samsung who will be able to give you a definitive answer..
