Please make sure your game was downloaded from the App Store/Google Play/One Store. If you have downloaded our game on other platforms, we cannot guarantee that it will work properly.

You can try the following steps to solve this issue:
1. Make sure you have enough free space on your device. If you do not have enough free space, you may not be able to install the game. You can try deleting apps or data that are no longer in use on your device to free up space, and then try installing again.
2. Check your network connection status. If the network is unstable when downloading the game, the game may not install correctly. You can try changing the network environment (Wi-Fi/LTE) to get a more stable network environment.
3. Update your device system to the latest.
4. Please check that your device meets the minimum requirements to run the game.

If the above methods do not solve your problem, please send the detailed information (such as the error message appeared or relevant screenshots) to our customer service centre, we will help you.
