[Cannot Download / Install the Game (Merged)]

They did something on their side seems to be installing now.

Same here opened a ticket two days ago.  Ran HijackThis (twice), DXDiag, WinMTR, disable startup services, and set to "run as administrator".   Nothing worked.  They seem to be in denial that it is a launcher/installer problem.   Really bad there is no way to escalate the problem with Customer Support or get the Community Managers attention.

Ticket submitted.  We will see.  Seems like a pretty obvious bug that should have been caught by QA.

I am having the same problem.

I am having the same issue.  Brand new account today.  Get the EULA screen then installation hangs.  Windows Event related to KERNELBASE.dll.
