Location [Q] GApps Core 4.4.2 failing to install

I installed CM11 on my sgh-t849 tablet.. it works but when i try to flash GApps Core 4.4.2 it fails and stop working.. can i just install the apk onto a external sd card and just install that way and it work fine or?

Ive searched but no luck so either im missing it or something
