You can modify an installation to install products that have not been installed or to remove products.

1. Make sure no SolidWorks sessions are active.
2. In Windows, open the Control Panel and run Add or Remove Programs.
3. Select the SolidWorks installation you want to modify and then click Change.
4. On the Welcome to the SolidWorks Installation Manager screen, click Modify the individual installation (on this computer).
5. On the Serial Number screen, verify that the appropriate serial numbers are specified.
6. On the Product Selection screen, select the products to install or remove.

   When modifying an installation:
   

   • No products are installed or removed by default, even if you specify a new serial number. You must change the installation action of each product or feature component.
   • To view the projected action for a particular component, click the component name (but not the check box). The intended installation action appears in the information field below the product listing.
   • You can click the check box next to the product component to change the installation action for that component. (For example, if you are installing or removing components, selecting the check box specifies that the component is to be installed or removed and clearing the check box specifies that the component is not to be installed or removed.)
   • When you change a component installation action from the initial specification, an asterisk (*) appears next to that component in the listing.
   • If a component has optional installation sub-components in it, a + icon appears next to the component. To see the available sub-components for a component, click the + icon.
   • If a component has been expanded to show optional sub-components, a - icon appears next to the component. To collapse the sub-component listing, click the - icon.
7. On the Summary screen, click Modify Now.
8. On the Installation is Complete screen, click Finish.
