Arduino Create can not find USB port and Uno


I just installed Create on my computer. I use Windows XP Pro SP3 and Firefox 44.0.2.

Create will not recognize my Arduino Uno R3 and USB port. It just give a red cross in front of the Uno selection.

I have uninstalled.

Hope someone has a solution. In the meantime I go back to using 1.6.7.

Hi! Is the 1.6.7 recognising your UNO? In other words I am just making sure you have the windows drivers installed.

What did you uninstall? If you see a red cross by the UNO in the dropdown it just mean it is not connected in that given moment. It would be really helpful if you could post a screenshot. Thanks!
