Hi,
I just connected my new Arduino Uno and am going through the setup guides. I loaded the example code "blink" and went to upload it and it says error, can't access com3 port.
avrdude: ser_open(): can't open device "\\.\COM3": Access is denied.
I'm using windows 10, I've been through the troubleshooting guide on Arduino.cc and the only thing in the access section seems to me to be applicable is the fact I have Kaspersky installed which might act as a firewall...
I turned it off and still no joy.
I've tried other USB ports and restarting. I've tried reinstalling IDE and updating the drivers...
Any help would be appreciated.
Cheers.

Re: Com port access denied
Problem Solved.
I uninstalled IDE version 1.6.8 and installed version 1.6.7 and now it works just fine.
