Google play store is missing after installing Cyanogenmod 12.1 I installed CyanogenMod 12.1 to my galaxy S2(GT-I9100) along with gapps. (Later I tried the same with different gapps too) and everything went good, I successfully installed both zip from CWM 6.0.4.x.

But after I switch on my phone, after all initial steps, I noticed Google Play app is missing, all other gapps are present.

I have used same gapps file for installing in Galaxy note (GT-N7000) along with CyanogenMod 12.1 and Google play store is present

This is first time I'm facing these kind of issue with CyanogenMod installation.

Anybody can help on this issue?
I forgot to wipe system partition. I just performed factory reset and wiped dalvik cache.
After wiping these and installing gapps again worked for me.
