Check your phone whether having enough space for the app. Normally it requires more space than the size of the app during installation.

If your phone has enough space, try to clear both cache and data for your Google Play in App Manager and perform a restart for your phone after clearing cache and data. It should work afterwards.

Hope it helps =)
