I am trying to install Autocad Structural Detailing trial version on Windows 7
I installed microsoft .net 4.0 latest version, all windows updates, then autocad, with antivirus disabled. No installation problems.
At first run, i get an error message "the license has expired and cannot be extended", then autocad crashes.
I tried deleting files in the Program data/Flexnet folder, tried to change permissions of this folder to full control for users "everyone" and for the main user (which is admin), tried to start autocad with a new admin account, none of this worked.
