Betcha never flashed your F165 for Windoze 7, then Windoze does some stupid USB upgrade (security aka keep the CIA backdoor open) and bingo. Now you need an XP or Vista box to run the flash update for your F165..
This new release includes a menu option to update the USB firmware on your generator to support MS-Windows 7. Those who plan to switch to MS-Windows 7 MUST do this update to their generator BEFORE switching to Windows 7. To be able to do this update, you need a Windows system that can communicate with the generator. This can either be a Windows XP or Vista system or a Windows 7 on which you were able to install the USB driver and communicate with the generator PRIOR to doing the USB update. Some Windows 7 systems will not be able to communicate with the generator without this update. Prior to switching to Windows 7, please download F100 , install it, connect your generator and turn it on. Then sellect tools->Update USB firmware. Then turn off and on your generator. After this, a new USB driver will be installed. On most systems, this will be done automatically by Windows. On others, you will have to install it manually via the MS-Windows Device manager. The new USB drive is located in c:\Program Files\f100\usb
