If the download and installation process is running slow, there are several temporary solutions:
First, players should try temporarily disabling the firewall and anti-virus. Default Windows firewalls will come on automatically after others are disabled, so keep in mind that the Windows firewall may need to be disabled, too. Always remember to turn them on again after the download completes.
Players can also try opening the following ports on their router:
•TCP / UDP Ports 24100 through 24131
•TCP / UDP Ports 24300 through 24331
•TCP / UDP Ports 24500 through 24507
If that doesn't work, they can try bypassing the router and plugging the computer in directly to the internet source to improve download speeds
