PROBLEM:
The following errors are encountered when attempting to activate eLink for Windows, eCharts for Windows, or JeppView for Windows:

"Unable to connect: Error -1 (Invalid socket)"

CAUSE:
The Activation Wizard is unable to establish a connection to www.jepptech.com to complete the activation. This can occur if an Internet connection is not available, or if a firewall or network security application is blocking www.jepptech.com or the eLink, eCharts, or JeppView applications.

To verify if www.jepptech.com is blocked, open a browser and go to www.jepptech.com. Alternatively, launch Windows Powershell and run the following command:

Test-NetConnection -ComputerName www.jepptech.com -Port 80
