When upgrading the SolidNetWork License Manager, you must uninstall the old license manager before installing the new one.

1. Start SolidNetwork License Manager (Start > Programs > SolidWorks version > SolidNetWork License Manager > SolidNetWork License Manager).
2. Verify that no client computers on the network are running SolidWorks.

   The License Usage tab shows clients running SolidWorks.

3. If you wish to transfer the SolidNetWork license to another computer, transfer the license to that computer before removing the SolidNetWork License Manager from this computer.
   For information about transferring SolidNetWork licenses, see Transferring a SolidNetWork License.
4. On the Server Administration tab, under License Server, click Stop.
5. Click OK to exit the license manager.
6. In Windows, open Control Panel > Add or Remove Programs.
7. Select SolidWorks SolidNetWork License Manager, click Remove, and confirm the deletion.
8. In Windows Explorer, delete the SolidWorks SolidNetWork License Manager folder.

   (Typically, this folder is located under Program Files in the SolidWorks installation directory.)
