Error writing firmware... dfu-util not installed

After entering the command ‘particle flash --usb tinker’ the following message is

‘running dfu-util -l’

and

‘Error writing firmware…dfu-util is not installed’.

Photon is breathing cyan connected to USB. I am trying to connect a Nexus 6 tablet to Photon over WiFi using the Internet.

How do you install dfu-util in Windows 10?

Just download it, save it somewhere and add it to the PATH.

You can also use

particle flash -serial tinker

which doesn’t require dfu-util.
