Group: Forum Members Posts: 4, Visits: 38	Hi, I've got a batch file which runs three scripts. Everything works fine on one of my laptops (Windows 8 with Chrome), but on another (XP with Chrome) I get the following popup message when the Start button is pressed (to begin the study): "Inquisit was unable to contact the server to verify that this script is licensed. The script will not be run." Any ideas why I'm getting this message? I do have a license. Thanks.

To enable TLS support under XP, see http://blogs.msdn.com/b/kaushal/archive/2011/10/02/support-for-ssl-tls-protocols-on-windows.aspx

If the issue is indeed due to a firewall (local or on the network perimeter), the participant needs to edit the firewall's rules to allow Inquisit to communicate with the server.
