Roberto, I just replaced my laptop where I had my reef angel software connected. The old laptop was running Vista. The new one is Windows 7. I downloaded the installer and it was unable to find any ports. I opened Arduino and went to the tools menu but the serial ports are greyed out. Any ideas?

Did you plug the cable in the new computer?
Was the driver installed correctly?
If you go Control Panel->System->Device Manager
And expand Ports (COM & LPT), do you see USB Serial Port (COMX)?
Do you have any device with yellow exclamation mark?

I looked under the device manager and no com ports were listed. I have universal serial bus controllers, system devices, human interface devices and others that are self explanatory

Is the USB cable plugged in on the new computer?
Do you have any device with yellow question mark?

The USB cable was not connected when the installer said to make sure it was not. The installer then said to connect the USB cable and proceed, which I did. The next screen showed there were no ports available. The USB cable was connected to both the laptop and the controller. I verified the connection at the controller (black wire on the right side and plugged in to the far right)

If windows does not even recognize the cable, it is not installed correctly.
Try updating the driver:

Windows recognizes when the cable is plugged in to the computer. I get a pop up stating a new device has been plugged in

If it says a new device is plugged in, it indicates that the drivers were definitely not installed properly.
It should say nothing and should show the device in your device manager window.

Just to clarify, when you said it is not installed correctly, are you referring to the driver? If so do I install the driver from the link you provided or start the installation with the installer all over again?

Try the driver that I linked above.
Those are just the drivers for the cable.
The installer usually installs the drivers automatically, but it seems something went wrong because the cable is not setup properly.
