App download repetedly stops at 83%

I have a Nexus 4 with Android 5.0.2. I have tried repeatedly to download Airdroid but the download stops repeatedly at 83%. Google Play then says Airdroid is being installed, but nothing happens - I have left it this way for up to two hours.

Any suggestions?

CORRECTION - That's Android 5.0.1

Try downloading the .apk from home page: www.airdroid.com
