Once it’s done loading into C: Program Files, open it. But if the arduino software is zipped, you’ll have to unzip it. (Here’s how to do it: Open up another C:. Click on make new folder. On the first one you opened, double-click on the software for the arduino. Once it’s opened, you drag the entire folder(( yes, the folder that contains the IDE)). ) Once it’s done doing that, click on the unzipped arduino folder. Once you open that you should see a folder that says arduino. Right click on that. Click on create shortcut.
