C:\Program Files (x86)\Arduino\libraries\RobotIRremote\src\IRremoteTools.cpp:5:16: error: 'TKD2' was not declared in this scope

int RECV_PIN = TKD2; // the pin the IR receiver is connected to

This report would have more information with

option enabled in File -> Preferences.

Try renaming this folder "C:\Program Files (x86)\Arduino\libraries\RobotIRremote" by inserting a space in the folder name. eg."C:\Program Files (x86)\Arduino\libraries\Robot IRremote")
Restart arduino IDE. The other lib will be chosen.
