Some time ago we run into following problem. When trying to install Enterprise Portal axsetup.exe crash wile retrieving the list of the sites with following error in installation log:
The issue happens when one of our IIS Web Sites are having only one binding which is https binging i.e.:
The problem is that axsetup.exe does not able to retrieve secure bindings but only standard bindings. Because there is no standard binding for this page axsetup.exe is unable to get port information for the site and then crashes. To workaround this issue:
1. If the site running only https binding is not the site where you wish to install your Enterprise Portal you can just stop the site then axsetup.exe will not try to get info for this site and will not crash.
2. If the site running only https binding is the one where you wish to install your Enterprise Portal then you can add to bindings temporary standard bindings (http). Then after axsetup.exe finish installation you can again remove it
