Not using the Enterprise License Manager when needed
If you are using an Enterprise license, but are not using the Enterprise License Manager. If this is the case, you will see "Error 1303" appearing in the Network License Manager's log file. Please download the Enterprise License Manager to proceed. To do so, follow these steps:
- Go to the Downloads page and sign in if requested.
- Select "Get License Manager" under the I WANT TO menu.
- Click the blue button labeled 'Download for <OS/Platform>" under the Enterprise License Manager section to download the Enterprise License Manager.
Connection issues
It is possible a firewall is blocking the client and Network License Manager from making a necessary socket connection to each other. If you are using software such as Zscaler, please allow the client and Network License Manager to communicate with each other, and ensure that a connection socket can be made on the computer hosting the Network License Manager and the client can connect to the socket.
