Troubleshooting Common SolidNetwork License Issues

July 6, 2021

SolidNetwork or floating licenses (SNL) can be convenient for your company with multiple users. A set number of licenses can be shared on multiple computers offering greater flexibility of usage.

You can have as many client installations of SOLIDWORKS and be able to access your network license from any of them as long as the licenses are available and a network connection is established with your server.

Due to its nature, it can be hard to identify what’s wrong when an issue arises and the issue could impact everyone.

Below are a few categories of issues you might face and tips on how to troubleshoot them:

1. Connection Issues between your computer and the server

• Check your client SNL manager has the correct servers name listed in the server list. It is usually 25734@yourservername

• If you are unsure of your server computer’s name, one way to find out is by going to command prompt inside the server computer

Type: hostname and press ‘enter’, the device name will appear below.

iii. Type: telnet yourservername yourportnumber and press ‘enter’

* yourportnumber is likely 25734 and 25735 by default in your installation, perform the telnet test twice to check both numbers.

Do check that under SolidNetwork License Server Information:
“A firewall is in use on this server” is enabled if present
Port numbers: 25734
Vendor Daemon Port Number: 25735
You can access this info by trying to reactivate the license using your SNL manager.

iv. A successful Telnet test will simply show a blinking cursor and nothing else on your command prompt window.

v. A failed test will show your command and tell you the connection failed. You should check that your windows firewall ports are open for two-way communication in the Windows Firewall advanced settings.

• Check your Registry Editor for server name

i. Search and open “Registry Editor” from Windows Start menu.

HKEY_LOCAL_MACHINE→SOFTWARE
→FLEXlm License Manager

HKEY_LOCAL_MACHINE→SOFTWARE→Wow6432Node
→FLEXlm License

iii. Find “SW_D_LICENSE_FILES” and double-click it.

iv. Check if the server name stated is correct. If not, overwrite the server name. Do not change anything else in the Registry Editor.

2. Using a newer Client version with lower SNL Manager Server version

• The version of SNL Manager server must be the same or newer compared to the client computer’s Solidworks application version.
Eg. SNL Manager server 2020 is not compatible with Solidworks 2021, but compatible with Solidworks 2020 and earlier versions.
To use Solidworks 2021, you will need SNL Manager server 2021 and higher.

• One way to upgrade your SNL Manager Server is from the installation manager in the installation of a new version.

• After upgrading to a newer version of SNL Manager server, do reactivate the licenses before using.

You can refer to 3. SNL Manager Server has not been reactivated since last renewal/purchase of licenses for reactivation steps.
