Qlik Sense Server Installation Win Server 2019 with Port 80 in used

[snowman]

Hi there,

I am trying to install Qlik Sense Enterprise in Windows Server 2019 as a single node, but found that Port 80 was in used. On further checking it was used by PID 4 which is a system process (ntoskrnl.exe). The process cannot be "End Task". 

I searched the forum and there was a post saying that by default Qlik Sense uses HTTPS which is port 443. 

Can I simply ignore Port 80, and continue the installation ?

Thanks

Qlik Sense does not listen to port 80 by default. 
Is the installer failing?

The installer prompted that warning, and struggled for a few days.. Eventually try ignoring the warning and seems the installation is ok. Wondering if using https, it only listens to port 443.
