Hello,
Ive got a Nano ESP32 to run a project on and windows will install the COM port (i can get device info in IDE and IDE recognises device name) but in either the RGB flashing mode or solid green mode i cant program the device.
The device manager shows no driver can be found for "Arduino DFU":
Ive pointed it at the ardino drivers folder, tried with latest version 2 IDE and older version 1, no luck.
Where can i download the DFU driver? Had a good look without any luck.
What Windows do you have?
Did you try to search the forum before posting a message?
I see a half dozen threads about the subject...
For example
Hi, Its W10 and i don't have admin rights (work PC) but its reasonably lenient, i.e. i can add/remove the IDE, normally drivers install without an issue etc
Everything on the forum suggested things like resetting the MCU or changing settings but this doesn't work. Reinstalled IDE, no effect. Windows just wont find the driver.
I have a W11 machine too which did locate and install the driver so I know the hardware, cable etc are all fine.
None of the solutions which are online, the forum, chatgpt etc suggest work.
Just very stuck and confused why there just isn't a "download drivers" option somewhere. Any help would be appreciated.
Many thanks 
Hello @stuartsjg, those drivers are installed when the IDE installs the Arduino ESP32 Boards package by Arduino, so try uninstalling and reinstalling that in the Boards Manager. Note that there's a different one that is simply called esp32, but does not include drivers.
When the one by Arduino is installed, a popup should appear and ask you to confirm installing the required driver. If this does not appear, then it looks like you don't have sufficient rights on your work PC. 
Thanks for the info, ive removed and reinstalled the library, "2.0.18-arduino.5", but still not found.
Where does the IDE store the boards library and driver? The IDE has installed here
C:\users{User}\AppData\Local\Programs\Arduino IDE but i cant see an obvious drivers folder.
It was so I could manually point the device manger to the drivers folder and force it that way as i normally don't have an issue with permissions and installing drivers.
