isite installation problems

Hi,
I downloaded isite from idirect web site, and uncompressed it, and installed in the pc. fine.
but when I go to run the program, it does not appears anywhere. in the start menu I see the idirect folder, the isite api subfolder and then only comes uninstall isite api. I just tried to download again 3x, and tried to install in 3 different pc´s, but no changes. just called the idirect tec. support, they says that there is no problem with isite.
please, can somebody help?
thanks in advance
