Please ensure you have adequate storage (more than 2gb) on your device to install the new game. Also, please make sure you enable applications from untrusted developers in your system settings!
Some users had trouble even when they take these precautions, and some devices may react differently when you open the downloaded file from your browser vs. your system files. Please try opening the file from each of these locations if you are having difficulty.
If you are still unsuccessful installing the game, please send us an email and we will do our best to assist you!
