Moving SOLIDWORKS Network License Manager to New Server


When moving your SOLIDWORKS License Manager to a new or temporary server, there are several steps you can take to make your life easier and minimize or even eliminate any downtime for your SOLIDWORKS users.

This involves some setup on the Server machine and Client machines, but if you follow these steps, the actual switch over for Server machines should only take a few minutes.

We will focus on the NEW Server Location first:

Step 1)

If you are using a Windows Firewall on your New Server Machine, you will need to add TCP/IP Port exceptions for both 25734 and 25735 as both Inbound and Outbound “Allow” rules.

Step 2)

We need to Install the new Network License Manager. This can be done either via Installation Media (DVD) or via a Download from the SOLIDWORKS Customer Portal.

Once you launch the Installation Manager, make sure you only install the SolidNetWork License Manager found under Server Products.


Complete the install, but DO NOT ACTIVATE the New Server yet!!!


For the next few steps, we now need to point each Client computer to the New Server Location.

Step 3)

On each Client computer, launch the SolidNetWork License Manager Client found either by searching SolidNetWork License Manager Client 20XX or under All Programs > SOLIDWORKS 20XX > SOLIDWORKS TOOLS > SolidNetWork License Manager Client 20XX.

Once launched, go to the Server List tab and Add your New Server Location by typing in port@servername, ex. “25734@servercomputername”.

If you get this error, hit Yes to add the server anyway as we haven’t activated the New Server Location yet.

Once all of the client computers are pointed to the New Server, all we have left to do is Deactivate the old Server and Activate the New one.

Step 4)

To Deactivate the Old Server:

Launch the SolidNetWork License Manager Server 20XX on the Old Server and under Server Administration > Modify > Move your product license(s) to a new/upgraded computer.


Once the license has been deactivated successfully, it’s time to activate the New Server.

Step 5)

On the New Server Location, launch the SolidNetWork License Manager Server 20XX and under Server Administration > Modify > Activate/Reactivate your product license(s)

If a firewall is in use on the New Server, make sure you select the Firewall option under Server Information.

And finally, hit Select All when prompted for which license(s) to activate and perform the activation Automatically over the Internet.

Once your New Server is Activated, the last step is to remove the Old Server location from each Client computer by launching the SolidNetWork License Manager Client on each computer and under Server List > Remove.

And that should do it!  I hope this helps makes moving Server computers a little easier.
