Why I can't authorize my arcgis 10.2 for desktop basic? everytime i tried to authorize it, it says "Unable to send your authorization information to Esri via the internet." I have internet connection, and Arcgis.com is up. I don't know what's the problem. Please help me to authorize my arcgis 10.2
Try offline authorization, if that helps!
offline authorization is cumbersome. sometimes your license will get corrupted when try to do multiple authorizations/de-authorizations within short period of time. Is there any specific ports, URLs we need to allow access from Firewalls and proxy servers?
Hi Bernard,
It could be a firewall issue. Asrujit is right. Go for an offline authorization. Save the text file and mail it to authorize@esri.com .
You will get the license file on your mail from Esri. Use the steps mentioned in that mail to authorize the license.
