Currently the launcher will finish it's rounds checking the download of D3, but when it goes into the install portion it hangs up while updating setup files. The load bar will continue loading and hope from 3 different positions.
I have let it run for over an hour before closing it and over 20 minutes multiple times.
I am plugged in via Ethernet directly into my router and have no connectivity issues. Should I try redownloading the install files again and try it then?
