Unable to install ArcGIS Web Adaptor (SII)

Tried 10.1 and 10.2, the same issue:

My OS is Windows Server 2012. ArcGIS for Server has been well installed. When I proceed to install Web Adaptor, it comes the

"Error 2878. On the dialog WebSite List the control ListBox1 has a possible value: xxx, 80, 2. This is an invalid or duplicate value." where xxx is a HTTP website on this server.

Checked posts about this issues, I got two suggestions:
1) Change the binding of the existing site to a different number, say 8080. However, the number in the error changes as well, to 8080. I've also tried to stop the existing site or delete the entire banding. But nothing works.

2) Install from command line. I've got another error:
"Error 1606. Could not access network location \arcgis"
When I change the parameter VDIRNAME to something else, the error remains and the directory in the error changes too.

Anyone can help me on this?
