Cant launch Diablo 2 and can't see the game on battle.net software battle.net

Hi, I just bought and downloaded the diablo II classic game on my Windows 10 laptop. However, I cannot launch the game. I have tried to download the game both in English and Chinese( I am located in China), but the game still won’t launch. It always show a black screen for a few seconds and poped back to windows. I tried to launch on the battle.net software, but I cannot even find the game on that software. Any advice? Thanks
