Why is my play store app not installed in my phone after hard reset?

[AC Question]

Hi, my phone hanged when i tried to start it up and failed to do so after few tries. Then i tried to hard reset it and it works. However my play store app is not working, it turned grey with a SD card logo on it. What shall i do in this situation?

Welcome to Android Central! Which phone? Did the phone originally come with Play Store preinstalled?
