Are you sure the download completed successfully and unzipping showed no errors?
Is there space on your device to store the 12 GB of game files?
Verify you followed carefully the instructions on “How to play on Android”, above on this page.
To add on to this, your error states that you are missing core files of the game. So this error is a result of a failed installation.
Thank you very much!!
I'll try to download the zip file again and do the complete passages.
