I have a windows server 2012 computer, it has IIS version 8.0. I have installed ArcGIS 10.5 Server very successfully. However, when I try to install WebAdaptorIIS, I get an error, like this and then the installation stops there:
Just a cross-check if the listed IIS components have been enabled.

Thanks Jayanta Podder, after cross-checking and adding in the mentioned IIS components, I was able to install without any issues.
