unable to install on 64 bit windows 10

Hi, do you have source code of this driver?

[HobbyComponents]

It looks like hardware issue with the device you're trying to connect, not the CH340 driver. Did you buy it from us? If not I suggest you contact whoever you bought it from. Andrew

I'm afraid not. We're not the original creators of this driver and are just making it available here for our customers to download. Andrew

I had a problem on Windows 10 as well -- cloned the repository and tried installing, but got this "hash missing" error:

i also can't install this on my windows 10 machine, firstly some of the files will only save as html files and when I try to run the exe it says this is not compatable with windows 10 and that I should ask the file developers for an updated version :/

Hi, I Received my Arduino Uno-compatible CH3401 HCARDU0119 but could not load any sketches. I wanted this to be a development board to develop programs for my Uno + board purchased from you sometime back, now embedded in a controller and it has worked very well but Uno + is currently out of stock.
Unplugging the UNO+ from my laptop connecting the new board and verifying the sketch is OK, but when I try to upload it I get the following error message;
avrdude: ser_open(): can't open device "\.\COM6": Access is denied.
Failed uploading: uploading error: exit status 1
I am using a Windows 10 64bit and IDE 2.2.1. and fine with the Uno+. I have tried to download the Windows link from your product site but my McFee blocks the file as unsafe.
Both boards were purchased from you and the UNO+ is brilliant but not so sure about this HCARDU0119 compatible board.
I am hoping there is an easy fix with a new Windows driver that my virus checker does not reject otherwise I may have to return this board and with for the Uno + to come back in stock.

Hi Terry,

avrdude: ser_open(): can't open device ".\COM6": Access is denied

The above error suggests that the Arduino IDE, or in particular AVRDude (the command line program the Arduino IDE runs to upload sketches) cannot access the COM port because something else is currently using it. This is usually one of two things:

Either AVRDude has previously locked up and is currently tying up the COM port. When you then attempt to upload a sketch again, the IDE runs a second copy of AVRDude which then cannot get access to the COM port. If you haven’t already, a simple reboot of your computer should fix this.

The other likely cause is that there is some other software on your computer that is grabbing the COM port before the Arduino IDE can access it. Sadly Windows doesn’t make it easy to determine what is currently accessing a COM port but they do have a tool called process explorer that may be able to tell you what’s causing the problem. You can download it from the Microsoft website here:

National instruments has a good guide on how to use it to find what software is using a particular port here:

Could you give it a try? If this doesn’t fix the issue let me know and we can try changing the COM port.

Hi Andrew, Many thanks for your prompt reply but since my comments I have discovered that it’s the latest version of IDE that’s behind the problem. I have reinstalled an earlier version of IDE at that has resolved the problem so able to upload my sketches. It’s not an ideal solution as it’s throwing up errors with my sketch that run well on the UNO +. The new IDE2.2.1 is also colour coded and very helpful when writing code, and not available in older versions of IDE. I will check out what you have suggested but concluding it’s the firmware program in the new Arduino the issue as it’s not compatible with the IDE2.2.1 but is with earlier versions of IDE.
