Hello! The program installs perfectly and starts under Win7 professional. My problem is that there is an original interface, but its serial number is different, not 100251. But it's still 6 characters. However, the program says that since the registration of the serial number is different, I will not be able to do any diagnostics with it. And really. When connecting to the car, it says that it's an internal error. Is there a solution for it? Thanks!
