Perhaps I solved the problem.
Was necessary to install the software DVC3 where are included the new driver for DVC3 interface. Now, the softwares DVC2 and DVC3 seems to work properly. But, unfortunately, tool.exe still does not detect the interface.
I have installed, the inteface on 2 PC, one with s.o win XP pro 32 bit and another one with s.o windows 7 pro 64 bit , but tool.exe does not detect the interface, although it seems to work. Only Monday I'll can connect some fixtures at DVC3 gold.
Do I the correct thing, but I don't understand why tool.exe does not see the interface.
Sorry for my horrible english.
