A client purchased a license to AutoCAD 2015 and needed it installed. After the installation completed, during the first run it resulted in a “Establish an internet connection to continue” error.
As per AutoDesk documentation, we rebooted, we renamed the C:\Users\<username>\AppData\Roaming\AutoDesk\ADUT folder to ADUT2, but got nowhere.
Finally after some digging, we were able to determine that due to the POODLE SSLv3 vulnerability last year, the installer was using an outdated SSL library to communicate with the AutoDesk licensing servers. Killing all AutoDesk-related applications by going to Task Manager -> Processes -> sort by description -> End all tasks that start with “AutoDesk…” and then applying the hotfix located here, we were able to open AutoCAD properly and finish the licensing process.
