I searched all over the web for this error but havnt found it. here is the code and error message.

Arduino: 1.6.8 (Windows 10), Board: "Arduino/Genuino Uno"

Build options changed, rebuilding all
Multiple libraries were found for "IRremote.h"
Used: C:\Users\Owner\Documents\Arduino\libraries\IRremote
Not used: C:\Program Files (x86)\Arduino\libraries\RobotIRremote

Sketch uses 10,188 bytes (31%) of program storage space. Maximum is 32,256 bytes.
Global variables use 469 bytes (22%) of dynamic memory, leaving 1,579 bytes for local variables. Maximum is 2,048 bytes.
avrdude: ser_open(): can't open device "\.\COM3": Access is denied.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

and here is the code...

#include <IRremote.h>

irrecv.enableIRIn(); // Start the receiver

}

// 1 if newval is equal, and 2 if newval is longer
// Use a tolerance of 20%

return 0;

    please help I used to know how to fix these things but has been 5 years so I'm a little rusty.

I fixed the com3 but I cant find the robotirremote in my libraries? only the ifremote and I ned this code.
