I have access to ESRI products through my organization. After downloading ArcGIS 10.7 I tried to get the authorization number but the licensing tab that I have used before only shows Developer option but not the usual licensing options. See attached screenshot.
Thanks in advance
Sorry for late response.
We investigated, and see that you don't have any permissions to do licensing on My Esri.
You can verify this yourself by going to My Profile and viewing what permissions you have. Full instructions on how to see what permissions you have can be found in this blog article.
To request the missing permissions, you'll need to fill out and submit the Request Permissions form.
