Using Arduino Installation & Troubleshooting
#1

When I compile my code, I see:

Multiple libraries were found for "Adafruit_MCP23017.h"
Used: C:\Users\Owner\Arduino\arduinosketchfolder\libraries\Adafruit_MCP23017
Not used: C:\Program Files (x86)\Arduino\libraries\Adafruit-MCP23017

When I go to C:\Program Files (x86)\Arduino\libraries I do not see anything from Adafruit. I did accidently put it there in the past but have removed it.

I'm running version 1.8.3.

The program works fine but do not like anything less than a clean compile.

Thanks,

Rick

Maybe try having the Operating System search for "Adafruit_MCP23017.h" and see it if shows up in any other directories.
