Hi, I am trying to install ArcGIS 10.7 on my personal desktop using my authorization code. I can get through most of the install steps, but the download process finished before the " I do not wish to authorize any extensions at this time. The extensions will be authorized automatically.", so I have never completed this step, or been able to finally input the authorization code. Do you know what might be the problem? I am choosing ArcGIS for Desktop Advanced Single Use.
