Question Trying to update to 4.4.2 via TWRP Flash getting error

I'm new to rooting and android in general. I'm currently running 4.4 rooted with stock I believe. Says ponury kernal in my settings.

I'm trying to flash the update for 4.4.2 via the TWRP install. I get a failed error: error executing updater binary in zip.

I've made sure my zip is the 4.4 to 4.4.2 but still no luck. Any ideas what I can do? Do I need to wipe something before I can put it on there?
