I have recently purchased a UNO.
I managed to get it to work on one computer with windows xp though there was no indication on the ports in the device manager that it was connected.
I have now tried to get it to work on my workshop computer, running windows 7.
According to the instructions on this site :-
Plug in your board and wait for Windows to begin it's driver installation process. After a few moments, the process will fail, despite its best efforts.
I have already downloaded and opened the files and can see them on my computer.
There is no indication from the computer that I have plugged the board in even though the green light shows on the UNO (I have a program running on the UNO that runs properly when plugged in?
I have plugged a memory stick into the usb port and the computer recognises the stick and allows me to download stuff from it so the port is ok. I have put the UNO back on the windows xp computer and it works.
On the xp I ignored this step and went straight to :-
Finally, navigate to and select the Uno's driver file, named "ArduinoUNO.inf", located in the "Drivers" folder of the Arduino Software download (not the "FTDI USB Drivers" sub-directory).
I located the file and clicked to open it. On XP this worked but on the windows 7 It opened in notepad -after all it is a .inf file?
I have been trying all evening to get round this and run the software on this computer. If I click on the arduino application in the arduino directory it opens up a box asking me if it can run , when told to it shows the blue box that is the first page loaded when running properly, leaves this on for about 10 seconds and then removes it.
Can anyone see what is going wrong?

I have managed to find the usb port it is in device manager under unknown devices, I have loaded the driver and it now shows up in the ports as arduino uno3 (com4) but nothing else worked and if I click on the application in the uno directory it still just opens a notepad page with the ,inf file.
