I am unable to install SC2

I have a buddy who just recently go into SC2 so I was gonna reinstall it but when I tried it would get stuck loading after hitting start install but it would also take 5-10 mins to get to that screen from the previous one. I have restart my PC reinstalled Battlenet and deleted files and the works I’m just trying to play a game with the homies. Plz Help

Do you have enough space to install the game?
What’s going on in Task Manager when you are trying to load the game? How’s CPU, Memory, etc?

I have a Tb of space and it doesnt mess with anything with cpu and memory or anything along those lines
