Hi, I have your program Flasher5 Rev.3 sn °: 53206th. I'm using without any problem with a PC with WinVista OS. Now I wanted to use with a PC with Win7 Ultimate, I installed the latest version V2.00C, set the correct com, but the application software does not recognize the flasher. This software is compatible with Win7 Ultimate V2.00C? Do you have tips, tests to offer me? Best Regards Fabio F.
