I met this problem when I want to open SDK sample. I've re-installed SDK runtime for several times and it is stll not working. Besides, I used my ESRI developer license for authorization.
Please help me with it.
It's possible that your firewall may be blocking the transmission of your authorization info. Can you try the following?:
1. Log in under an Administrator account.
2. Go to C:\Program Files\ESRI\License10.2\sysgen.
3. Move the file called 'keycodes' to a different folder.
4. Rerun the Software Authorization Wizard.
Hope this helps.
