Installing the Arduino IDE was very straightforward. I simply went to arduino.cc/downloads and selected the "Win 7 and newer" option to download the IDE. When I opened the downloaded file, it automatically installed the IDE. I also followed the instructions in the SIK guide to download the SIK guide code folder and copy it into the Arduino/examples folder, and I confirmed in the Arduino IDE that the SIK guide code appears under the "Examples" item in the File menu. There were no difficulties during the download or installation of the IDE.
