The solution is on the asset store itself. The package you’re attempting to download requires Unity 5.5 at minimum. You’ll need to upgrade your editor version.

I have this a lot, for me it always is under the assetstore window, so if you close the asset store then you will find the importing window, that’s assuming that your unity version is up to date.
