Unable to connect to ardunio uno on Window 7 Pro

Hi all,

I hope someone can help.

I am a bit of a newbie to Arduino and I am unable to connect to my ardunio uno on my Window 7 Pro computer using Chrome browser using Arduino Web editor. I get the following message "No Plugin Connection. Uploading is disabled until you reconnect."

I have tried Mozilla Firefox but get the same issue. I have followed the getting started instructions several times and downloaded and installed the agent (version 1.1.60-8f8e4c0) and restarted the computer but nothing seems to work.

My Arduino is showing up as a device on the computer (Com10) and the lights are on. I updated the chrome browser as well (Version 61.0.3163.100 (Official Build) (32-bit)).

I can't find the reason why it's not working. What else should I try?

Thanks

Did you say YES to the CERTIFICATE during install ? Without that you will not be able to connect.

Same with any additional drivers, firewall permissions etc.

What colour is the CREATE icon in the taskbar ? (working should be teal / arduino blue)

Are you just a "user" of that computer or did you install as "administrator" which is the best option.

What is your internet connection as some ISP's may also cause minor issues.

Thanks ballscrewbob for your response.

I did select yes to certificate in Chrome etc. The create Icon is blue and I switched off firewalls temporarily but it seemed to make no difference.

However I have just uninstalled the Arduino_Create_Bridge and then ran through the getting started procedure again - this time using Firefox and this time it came up with an additional trust CA step. Thankfully the arduino is now working in Firefox! I'm very happy to have it working and will just use Firefox for my making!

Thanks again ballscrewbob!

The certificate pop up for firefox is a little different to Chrome. However you seem to have it as you want "working".

Odd as Chrome is usually a little easier to set up.

Maybe I spoke too soon... as I am getting the following error when I try to load Blink (or any sketch):

Executing Command: exec: not started

With the following log:

Flashing with command:D:/Users/willist1/.arduino-create/arduino/avrdude/6.3.0-arduino9/bin/avrdude.exe -CD:/Users/willist1/.arduino-create/arduino/avrdude/6.3.0-arduino9/etc/avrdude.conf -patmega328p -carduino -PCOM10 -b115200 -D -Uflash:w:D:/Users/willist1/AppData/Local/Temp/arduino-create-agent090745184/Blink.hex:i

When I checked the directory D:/Users/willist1/.arduino-create/arduino/avrdude/6.3.0-arduino9/bin does not exist. However there is a folder D:/Users/willist1/.arduino-create/arduino/avrdude/6.3.0-arduino9

There is no avrdude.exe that I can find anywhere on my pc. So it looks like the setup process didn't install all the files correctly. Is there a log file I could look at to check the errors in the setup process?

Or is there a way to manually copy the necessary missing files from somewhere?

Hi @swillis, can you tell us wha antivirus you are using? Can you try to add an exception there for Arduino Create agent? Thanks
