ArcGIS Desktop 10.5 single use authorization issue

EmilianoPetrelli

Hi to everybody,

I'm try to authorize my single use Advanced Developer license on a new laptop but no way to do it.

I've try every single options (internet, offline using My.ESRI portal) with no luck, also try to reinstall all the desktop application but I'm still in trouble.

This is what happend to me:

1. Open with admin privileges ArcGIS Administrator 
2. Select ArcMap Advanced Single Use and click on authorize...
3. I've selected the option "Register option by internet" and fill required information and click next until the form to enter the ESU number.
4. The registration process starts but hangs on "Authorizing software..."
