@Guled30 I sent you a link to the website where you can install the USB driver for your operating system 🙂 When you download the files, extract them and run the driver disk. Inside there is a separate folder for the "Legacy" version. For your machine, you will most likely need to run this version, sometimes twice. This will allow your code to upload to CoDrone. Let me know if you have any more questions.0_1566324632880_Screen Shot 2019-08-20 at 11.08.30 AM.png
