Someone please help!
I am unable to install my arduino, because when I plug it into my computer, the only light that turns on is the red one, there is no green light, therefore I don't see it when I click on drive manager.
I have windows 7 64 bit. I tried different usb connector and a different computer too.
Just yesterday I received my first Arduino Uno. I bought the original, both for supporting the developers and because I like the map of my country printed on the back
Anyway, concerning your problem, I noticed one thing (I have Win 7 64 bit like you). When connecting the board for the first time, before installing the drivers, it appeared in the Device Manager not under "Ports", but under "Other devices". At first I did not notice that, and I lost some time just trying other USB cables/ports. If you find it in the list, then install the drivers and it should work (I don't guarantee for the clone, but mine works perfectly).
