With the new version, I can not install the game. I cleared more than 7GB of memory but it still won't install.

I know what you mean I had the same problem. I did the same thing, but I just ended up putting it on an sd card in my phone to get it to work. It mght have to do with how as you play there is more data, so there might be a minimum amount of free space required as well in order to install.
