Changing Your SolidWorks Serial Number

NOTE: Click here for an updated version of this blog article (updated on 1/11/19)


There might be a time when you need to change the serial number used for your SolidWorks installation. For example, it is need if…

  • your company is changing from a stand-alone to a network license,
  • you have installed the wrong license on your system,
  • you’re moving your SolidWorks to a new workstation, or
  • you have completed your evaluation and need to use your permanent license.

To change the serial number that your SolidWorks installation is using for licensing, you DO NOT need to completely UNINSTALL SolidWorks. You can change it directly through the SolidWorks Installation Manager.

Releasing Current Install License

Since SolidWorks 2008, activations have been necessary for stand-alone and evaluation licenses. Prior to changing your serial number, you will need to release this information. To do so, open your SolidWorks application. In the Help pulldown menu, select “Transfer Licenses…” as seen below.

SolidWorks Installation Manager

To change the serial number:

  1. Go to the Windows Control Panel and launch “Programs and Features” (if you are using Windows Vista, Windows 7, or Windows 8) or “Add Remove Programs” (if you are using Windows XP).
  2. From the list of installed programs, find the SolidWorks installation, select it and click Change. (Do NOT Select Uninstall, if the only option available is Uninstall, then your SolidWorks was installed using an Administrative Image and you will need to have your IT administrator to contact DASI Solutions Technical Support for further instructions.)
  3. The SolidWorks Installation Manager will now launch. Select the top option, “Modify the individual installation” and click “Next”.
  4. On the “Serial Number” screen of the Installation Manager, you can now change the serial number to the new one that you want to use. (CRTL+V will paste the serial number into the 6 boxes.)
  5. Once the new serial number is entered, click “Next” through the rest of the installation screens without making any further changes.

These steps can also be used if you have purchased an additional license of SolidWorks Simulation, SolidWorks Motion, SolidWorks Flow Simulation or SolidWorks Workgroup PDM.

On the Serial Number screen, simply check the box beside the product you wish to add, then enter in the serial number. On the “Product Selection” page, make sure that the additional products that should be installed are selected. These should be checked by the Installation Manager as part of the entitlement check that happens after entering the serial number.

    Hello your post was a lifesaver! I installed the student version of solidworks but accidently put in the SolidWorks Composer serial number instead of the Solidworks serial number. When I tried to activate the product it would not let me. Thanks to your article I was able to successfully activate my SolidWorks!
