Activate/Deactivate Your SOLIDWORKS Product

You can activate, reactivate, deactivate, or display SOLIDWORKS licenses for your computer using the SOLIDWORKS Product Activation Wizard.

The Activate/Deactivate Your SOLIDWORKS Product page appears when one of these events occur:
  • You start SOLIDWORKS but the license for this computer is not activated.
  • In SOLIDWORKS, you click > Licenses > Activate.
  • In SOLIDWORKS, you click > Licenses > Deactivate .
  • When you start SOLIDWORKS, you click Reactivate Now in response to a Product Activation prompt.
  • In the SolidNetWork License Manager Server, under License Information, you click Modify > Activate/Reactivate your product license(s).

Before you can run SOLIDWORKS products on an individual computer, you must activate the license for that computer.

If you disable a computer or move the SOLIDWORKS software from one computer to another, you must deactivate the license to the license key server at Dassault Systèmes SolidWorks Corporation. Then, you reactivate the license on the other computer.

For details about activating, deactivating, and reactivating individual SOLIDWORKS licenses, see Administering Individual Licenses. For SolidNetWork licenses, see Administering Licenses Using a SolidNetWork License Manager.

Serial Numbers

If you are managing licensing using the SOLIDWORKS SolidNetWork License Manager, you can add serial numbers from the Activate/Deactivate Your SOLIDWORKS Product dialog box by clicking Add. You can enter or copy and paste multiple entries into the Add Serial Number dialog box. Use commas, semicolons, or press the Tab key to separate the entries. Do not use spaces to separate the serial numbers.

You can also remove serial numbers that have either not been activated or have expired by clicking Remove.

See Adding Serial Numbers and Activating SolidNetWork Licenses.



Select the Product listing to specify the SOLIDWORKS product whose license you want to activate or deactivate. Specify whether to activate automatically over the internet or manually by email.
If you are activating a SolidNetWork license, the SolidNetWork serial number appears instead of the Product listing.


Starting with SOLIDWORKS 2022 products, if you have perpetual commercial or educational licenses, you must reactivate those licenses once a year. A perpetual license never expires but needs to be reactivated. The SOLIDWORKS Product Activation prompts you to reactivate before the required reactivation date.

To reactivate a license:
  • If you have an individual license for your computer, click Reactivate Now at the SOLIDWORKS Product Activation prompt. If you do not want to reactivate the license immediately, click Remind Me Later.
  • If you are using SolidNetWork licensing, click Reactivate in the SolidNetWork License Manager Server, from the Server Administration tab. In the Reactivate Licenses dialog box, you can use the Serial Number drop down to filter for licenses that are expiring.

Contact Information

Specify an email address that the SOLIDWORKS software can use for license activation.

If you specify manual email activation, the SOLIDWORKS software sends the license key response file in an email to the contact address or to another email that initiated the request.
