If it's not in the app drawer, it's not installed. Downloading an apk file and doing nothing else doesn't install the app. Use something like MyFiles to find the apk file (it's probably in internal storage, in Downloads) and tap it - it should install. Then find it in the app drawer, long-press it and drag it to a home page if that's where you want it.
