Trouble uploading to Winc1500 (wifi) and Metro Express

I have a Winc1500 mated to a Metro Express via headers. I am running the Arduino IDE 1.8.5 on a Win10 machine. The program that I am attempting to upload to this setup is the "ScanNetworks" example without any modification. When connected to the PC, the Metro board has a green "on" led illuminated, the yellow "tx" led is on a fast blink, and another large led on the Metro cycles between red, green, and blue. Pressing and releasing the "reset" button on the Winc1500 causes the red "L" led to momentarily illuminate. My first question is: In the IDE "Tools" board drop down list, there is no "Metro Express" board to select. The only board close to some wifi is an "Arduino Uno Wifi" I have select this board only because it has "wifi" in the name. I have selected "COM1" for the port configuration. Attempting to upload the ScanNetworks compiled program to the setup results in the included messaging. I have not found what the "not in sync: resp=0xd2" error message indicates. Any help will be greatly appreciated.

avrdude done. Thank you.

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

If you have an Adafruit Metro board, you must follow Adafruit's tutorial to install the board support package. This will add the board to the board menu.

Thank you for the suggestion to update the IDE with more boards. It has worked and now have the ability to select the Metro MO Express board. There still exists a problem with the upload. A copy of the IDE messaging during the load is included in this message. After the load attempt completes the "L" led on the Metro is a slow pulsing red. The large led on the Metro that changes through red, green, blue is on one constant color. My question now is: Where are the java files that the IDE error messaging lists? Are they supposed to included in the IDE like "libraries" are? Or are the java files supposed to located as part of the "programs" within the Windows environment? Thank you in advance for any assistance that you may provide. The IDE messaging for the upload is as follows:

An error occurred while uploading the sketch

Try rebooting the PC. Also all Adafruit M0 boards require installing the Arduino SAM boards package as well as the Adafruit boards package.

The best place to ask about Adafruit boards is Adafruit's forum.

I have a Metro MO Express mated to a Winc1500. Adafruit indicates that there are three LEDs on the Winc1500 that indicate the status of the WiFi connection. My question is: Which library accesses these LEDs? The web page where this is indicated by Adafruit is: Pinouts | Adafruit WINC1500 WiFi Shield for Arduino | Adafruit Learning System. Further down the page under LEDs it states the following: There are 3 LEDs that are controlled by the Arduino library - they will let you know when there is WiFi access-point connectivity, Activity or an Error when setting up. I have looked through a very long list of libraries available on the Arduino IDE (1.8.5) and not located such a library. Please indicate the specific library required to allow the three LEDs to indicate the connection status. Thank you in advance for any assistance.
