How to Update the SOLIDWORKS SolidNetWork License Manager

Keeping SOLIDWORKS running smoothly in a networked environment depends heavily on ensuring the SolidNetWork License Manager is up to date. Without updating the SolidNetWork License Manager, you risk exposing yourself to security risks and falling behind with key functionality for end users.

The steps to update the SOLIDWORKS SolidNetWork License Manager are straightforward; however, there are a few things to think about and plan for ahead of time.

What Is the SolidNetwork License Manager?

The SolidNetWork License (SNL) Manager is the server application that provides SOLIDWORKS licenses to users on a network. Client machines have SOLIDWORKS configured to communicate with the License Manager service on the server.

The SNL Manager must maintain the following requirements:

• The major version matches or is newer than the client machines
• Activation is performed once per renewal cycle or once per year to refresh the maintenance status
• The SolidNetwork License Manager service is running

Why Updating the SNL Manager Is Important

Keeping the License Manager updated is more important than downloading the new, shiny version of the software.

SOLIDWORKS Version Compatibility

SOLIDWORKS clients require the license manager to be the same version or newer than the installed SOLIDWORKS version. If users upgrade SOLIDWORKS without the server being updated and reactivated first, an error message will occur stating that the version of the client is newer than the server.

Operating System Changes

Each version of the License Manager is tested and validated on specific operating systems. Consult the SOLIDWORKS System Requirements page to ensure support prior to any updates.

What to Consider Before Updating the SolidNetWork License Manager

Like many software upgrades, there are a few considerations before upgrading to protect yourself in case the upgrade fails.

Document License Information

A direct upgrade of the license manager can be performed, which will maintain license information. However, always keep records of your license information for reference.

Be sure to document:

• Serial numbers
• Server name and port settings
• Options file (if applicable)

Potential Downtime

Each SOLIDWORKS client has a heartbeat to the server to verify the service is running, which occurs every two minutes. If the service is not running, clients will receive a warning after ten minutes, and if a license cannot be obtained after 20 minutes, clients will be prompted to save work, and the license will be revoked.

A direct upgrade of the SNL typically takes less than ten minutes, so users are unlikely to receive any messages. However, consider updating outside of key work hours to account for possible delays.

How to Update the SolidNetWork License Manager

The upgrade process for the SolidNetWork License Manager follows a few key steps.

Download the Installation Media

The SOLIDWORKS Installation Manager can be used to install or upgrade the SolidNetwork License Manager, but it can also be used to install SOLIDWORKS on client machines. The download files are available at the SOLIDWORKS Downloads page.

Please note that access to the SOLIDWORKS Downloads page requires an active subscription and a 3DEXPERIENCE ID tied to your company’s subscription benefits.

Return Borrowed licenses

Before upgrading, ensure that all borrowed licenses are returned.

Deactivate licenses

While not required, it is best practice to deactivate all network licenses on the server.

To deactivate your license prior to upgrading:

1. Open the SolidNetWork License Manager.
2. Select Modify.

What to Do After Updating the SNL

Once the SolidNetWork License Manager is updated, it is best practice to verify the upgrade was successful.

After the update completes, check the following:

• The SolidNetWork License Manager service starts successfully
• Licenses appear correctly in the License Usage tab
• Clients can check out and return licenses
• The server name and port have not changed unexpectedly

Final Thoughts

Updating the SolidNetWork License Manager should be the first step in a mass upgrade to SOLIDWORKS and SOLIDWORKS PDM. Failure to do this first won’t spell disaster for an upgrade, but it will introduce unneeded downtime to the upgrade process.

The rest of the upgrade process for SOLIDWORKS requires upgrading the client machines, but with the SNL updated, it will go off without a hitch. The upgrade for process for SOLIDWORKS PDM requires a few additional steps and introduces more uncertainty for inexperienced admins.
