Hello,
I am trying to deploy ArcGIS 12.0 in our development environment. We are moving from ArcGIS Enterprise 11.5. I was able to install Portal without any issue, but when I go to install the Web Adaptor for Portal I am getting stuck.
After running the downloaded ArcGIS Web Adaptor (IIS).exe file the Set Up Wizard does not launch. When I go to the downloaded files at the specified installation path and run Setup.exe nothing launches either. I tried downloading a fresh file from MyEsri and restarting the process, but that has not helped either.
I have checked and verified I have the correct .NET 8.0.7 and Microsoft Web Deploy 4.0.
I tried to manually run ConfigureIIS as outlined here: https://support.esri.com/en-us/knowledge-base/only-one-instance-can-be-installed-of-arcgis-web-adapto-000038798#:~:text=Description,shown%20in%20the%20image%20below.
and received this error:

Any thoughts on what could be going on?
