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.

Download speeds are also related to internet connection speed, which can act as a limiting factor. If the overall connection speed seems slow, players can verify it through a third party source like SpeedTest. This site, and many others, will calculate internet connection speed (higher numbers are better). If it turns out that the overall internet connection speed is slow, we recommend the players to contact their Internet Service Provider and have them troubleshoot the connection with them.

Last but not least, they can change the Maximum Download Speed of the launcher. Click on the gear icon in the top right-hand corner to open up the Launcher Settings, scroll down to the bottom of the menu, and look for the section titled Maximum Download Speed. Click on the drop-down menu and select 5MBps. This should help speed things up!
