Messenger - App not compatible with your device

I have just bought a Mediapad x2. So far so good. Bigger than I expected, but supercool :)

But I cannot install a pretty large amount of apps. Of which Facebook Messenger, Whatsapp, Skype, etc...

I get the error message that the app is not compatible with my device.

Anyone else have that problem? How do I fix it? I fear I will need to root my device to fix it?
