Interface III and Win 7 64bit

Hello. I want to install the USB int III in my new windows 7 home 64bit but until now I was unable to do it. I connect the device, windows recognizes it but then fails to install the driver. Note that I have installed the firmware 1.4.80. I have installed it in a windows XP system with no problems. Note that in the past I have successefully used the interface in windows XP. I appreciate all the help.

Please try to connect the USB-Interface with your R/C transmitter first, switch on the transmitter and then connect the USB-Interface with your PC.

Finally I manage to correct install the interface. The trick was to keep moving the RC transmitter sticks during device installation. And this have to be done during all connects. So, if I disconnect the device, the next time I connect I need to move the sticks in order to get a proper installation of the interface. I can't understand why this happen. Perhaps you have some thoughts about this. Please post this behaviour in your forum, so other people can access this info. It would very nice that the forum be in both German and English, so the large majority of the people can understand...
