Activate/Deactivate Your SOLIDWORKS Product

SOLIDWORKS Product Activation enables you to activate, reactivate, deactivate, or display SOLIDWORKS licenses on this computer.

The Activate/Deactivate Your SOLIDWORKS Product screen appears if one of these events occurred:
  • You started SOLIDWORKS and the license for this computer is not activated. (You are in Activate mode.)
  • In SOLIDWORKS, you clicked > Licenses > Activate. (You are in Activate mode.)
  • In SOLIDWORKS, you clicked > Licenses > Deactivate . (You are in Deactivate mode.)
  • When you started SOLIDWORKS, you clicked Reactivate Now in response to a Product Activation prompt.

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 SOLIDWORKS licenses, see SOLIDWORKS Installation and Administration Guide.


Click the Product listing to select 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.
