I want to install Arduino drivers on an XP, 32 bit machine and Windows 7, 64 bit machine. Installation on the XP machine went almost trouble free. The only issue was that when I plugged the USB cable in, the new device was shown as an "unknown system device" in XP's device Manager. I installed the UNO driver for this device and it was redefined as an Ardunino COM 3 port.
No such luck with the Windows 7, 64 bit machine. No new devices are shown in Device Manager, although the machine beeps whe the USB cable is connected. I tried using the ".exe" driver file on the FTDI site. It opened a DOS terminal window and said the device driver was successfully installed. However, still no Arduino Com ports in Device Manager.
I tried the driver install on a second Windows 7, 64 bit machine with exactly the same results.
I hope someone can help. I've spent several hours trying to resolve this issue.

The UNO does not use the FTDI drivers. Unplug the UNO, go to the arduino drivers folder, right click on the UNO .inf file, and install. Reboot, plug in the UNO and see if it is recognized.
I tried your suggestion for this but the UNO.inf driver would not install via the "right click" method. Thanks for your suggestion anyway.
However, I was able to get a driver installed. I was incorrect in my original post. Windows 7 Device Manager showed the UNO as a "USB Serial Converter" in a rather long list of USB devices. I "updated" the driver for this device using the UNO.inf file in the Ardunio Language package (under drivers) and everything now works.
