Hi,
I own a Microsoft Lumia 640XL Dual sim. I was just trying out the project my screen app and no matter what i did it just doesn't work. I tried uninstalling the device through device manager and control panel, unplugging the USB and plugging it again and even after it re installs, still doesn't work. I do have an exclamation mark on the device's control panel that says driver error and that it's unavailable where can i dowload the drivers? Like i've mentioned before even after uninstalling them all it still doesn't work and still getting the same yellow exclamation mark.
