just tried 1.1, and it's the same result

i uninstall the both device in the device manager, clean out the regsitry ( i can only find the FTIBUS one though), point the driver location to the new folder when prompted, still wouldnt work

i did, it wouldnt let me install the usb serial port from the folder, the error code is "setup can not copy ftserui2.dll"

my usb driver is not working and it gives me an error when i try to install the v10 drivers, somebody help!! TIA
