Anyone know how to set up swype on galaxy s4?

[Minicooper]

I had it on my galaxy S2, but although I can find the option for continuous typing on the s4, it isn't highlighted, iykwim, so I can't select it. Any ideas?

i have google keyboard, it's free and exactly the same.... not sure where it came from mind you...I had the free swype trial and then it stopped working, and suddenly google keyboard arrived!

Thanks catsmamma, I'll give that a go. Just annoying as if was a default setting on the s2....
