How to install Google Play.apk

[Mo0s]

I tried installing it as a normal app. Should I install it as a system app?

What device/Android version? Why do you want to install Google Play - is it missing? What version did you try to install & where did you download the .apk from? Does your device support Google Play? Check here: http://goo.gl/DOuFB
