Manage Add-ins dialog box
An add-in is a small program that provides additional commands and features to Microsoft Expression Web. You install an Expression Web add-in the same way you install other programs. Once an add-in is installed, it is displayed in the Manage Add-ins dialog box, where you can choose to enable or disable it.
When you enable or disable add-ins from the Manage Add-ins dialog box, you must restart Expression Web to apply the changes.
On the Tools menu, click Add-Ins.
Do one of the following:
Enable an add-in In the Manage Add-ins dialog box, select the check box next to the add-in you want, and then click OK.
The selected add-in will be enabled when you restart Expression Web.
Disable an add-in Clear the check box next to the add-in you want to disable, and then click OK.
The add-in will be disabled when you restart Expression Web.
This procedure does not remove the add-in from your computer. To remove an add-in completely, you must uninstall it from the Control Panel.
