Modifying your standalone SOLIDWORKS installation allows you to add or change serial numbers, as well as update the components installed on your system. With the SOLIDWORKS Installation Manager, this process is quick and straightforward—you can make these changes without uninstalling the software or editing the Windows Registry.

Here are some common situations where you may need to modify your SOLIDWORKS installation:

  • Adding or updating serial numbers
  • Switching from a standalone license to a network license
  • Activating a newly received serial number
  • Updating your license after a trial or evaluation period
  • Correcting an incorrectly entered serial number
  • Adding additional SOLIDWORKS products or components to your installation

If you are switching to a different standalone serial number or moving from a standalone license to a network license, you must first deactivate your current license. To do this, go to Help > Licenses > Deactivate, and follow the on-screen instructions to complete the process.
