How to Change Your Serial Number

Mina Bassalious

The SolidWorks serial number cannot be changed from inside of the SolidWorks program.  It can only be viewed.  To change the serial number, you have to modify the installation using the Windows Programs and Features.  Please note that modifying an installation will not result in uninstalling the program; rather it will modify the installation to reflect the changed serial number. Modifying an installation is the recommended way to change your serial number.

Checking Your Serial Number

  1. Open SolidWorks
  2. Click on Help > About SolidWorks

Note: If Help is not visible in the upper left corner, then hover the cursor over the right hand side of the SolidWorks logo and the help menu will appear.

Changing Your Serial Number

To change your serial number, you will have to modify the program using the Windows Programs and Features; the process is described below.

  1. Click on the Windows Start button and search for "Control Panel"
  2. Select Programs and Features 
  3. Right-click on Solidworks 20xx Sp x.x
  4. Select Change
  5. Choose Modify the individual installation
  6. Change the serial number in the Serial Number step
  7. Continue through the modification until completed

Note: If an activation error occurs, it may be that the license is currently being used by another machine.  If you are unable to activate, please contact technical support.

    I tried these steps. The installer claimed it was going to download 344 MB of material. That didn't make any sense when all I'm doing is changing a 24 digit serial number, so I aborted the installation.

    Hi Steven,
    This is fairly common. The installer may be completing the installation of a particular add-in. Please call our tech support if you have any questions about your installation. 1-877-266-4469 Thanks.
