Setting up IPv6 connection for Trados License Manager

Setup the environment to allow for IPv6 connection.

Before you begin:
  • Make sure no license server is set in Trados Studio while setting up the IPv6 connection.
  • Make sure Trados Studio is not running while setting up the IPv6 connection.
To set up the IPv6 connection:
  1. Right-click the Windows icon on the taskbar and select System.
  2. In the Settings window, under Related Settings, click Advanced system settings.
  3. On the Advanced tab, click Environment Variables.
  4. If the LSTCPIPVER variable does not exist click New and in the Name field add "LSTCPIPVER" and set the value to 6. If it does exist set the value to 6.
Note:
  • Connecting to a license server with IPv4 or IPv6 is mutually exclusive. While LSTCPIPVER = 6 is set, it is not possible for Studio to connect to a license server via IPv4 and vice-versa.
  • To enable IPv4 again, set LSTCPIPVER = 4 or delete the environment variable.
  • Setting LSTCPIPVER = 6 has a system-wide effect, meaning that if there are other applications that use a Sentinel License Server (RWS apps or 3rd party) it will force them to use IPv6 as well.
