Game won't install

Trying to install Starcraft 2 again for the first time in a long while to play with some friends. But the bnet installer is stuck. When I click the install button at the bottom right all that happens is that it turns into that bnet moving symbol and stays there forever. I tried already giving firewall clearance and deleting and reinstalling some files, but nothing works. I didn’t have the same issues when installing D4 a month ago either, so I kinda doubt it’s anything to do with my configuration
