Did what I asked it to - installed Instagram on Kindle Fire HD
on 16 February 2014
I saw this video on YouTube: [...] where you can download the actual Instagram programme onto Kindle Fire HD (I've seen a lot of complaints re the Amazon app, sorry) and to do this you need the File Manager Free app. Which worked like a charm! This is only the second downloaded app I've ever attempted, and it went smoothly and trouble free and I now have Instagram installed on my Kindle.
I'm very happy to recommend this but do advise you watch the video first to see whether it's for you (you need the File Manager to download another app which has the Instagram on it).
