How to Modify Your SOLIDWORKS Installation

Modifying your standalone SOLIDWORKS installation is a necessary step to add additional serial numbers, switch serial numbers, or modify which SOLIDWORKS programs are installed on your system. SOLIDWORKS provides a quick and easy method to modify serial numbers or to choose which programs are installed right in the Installation Manager without requiring the software to be uninstalled or any manual changes to the Windows Registry.

Here are a few examples of why your SOLIDWORKS installation may need modified:

Procedure to Modify the SOLIDWORKS Installation

Step 1.

If you are changing to a different standalone license serial number or switching from a standalone license to a network license, then the current license must first be deactivated by selecting Help > Licenses > Deactivate… and then follow the prompts to finish the deactivation.

Note: this step is not necessary if you are not switching standalone serial numbers or if you are switching from a network license to a standalone license type.

For Windows 10 users, click the Windows Start icon > Settings > Apps & Features and then click Modify to launch the SOLIDWORKS Installation Manager.

Note: If Uninstall is the only option available, then SOLIDWORKS was installed using an Administrative Image controlled by your CAD Administrator, which requires a different procedure to be followed to modify the serial number in the Administrative Image options. Have your CAD Administrator contact MLC CAD Systems Support for detailed instructions.

Step 3.

Once the SOLIDWORKS Installation Manager is launched, select the option Modify your installation and click Next.
