You already have a Google account if you're using an Android device, right? So take advantage of it: Set up Google Drive on your computer. Or, since I promised "no add-on software", you can access your Google Drive through the web! Still on your computer, copy the APK to the top of your Google Drive folder. On the Co-Star, hit the V key and select and run Google Chrome. In the Chrome address bar, enter the magic URL https://drive.google.com/#my-drive You may have to login here with your Google account. Do so. Your Google Drive directory will appear. Select the APK file. Press Enter. Use the mousepad on the numeric side of the remote to select the "Download" button in the middle of the screen (if you don't see this, hit the V button and select Chrome again). Double-tap on the mouse pad. You should see "Download started". Unfortunately, Chrome won't install it for you, at least it didn't for me. Hit the V button, and select the Downloads app. In there, once your APK is fully downloaded, select it (sadly the APK is given a made-up name as it's actually store in Google Docs, so go by timestamp or filesize if you have more than one). You'll be asked if you want to install it. Do so. You are done! If you want the files to stay all in one place, just leave them in your downloads folder too.
