Load or unload a COM add-in

If you are a developer, at some point you might need to load or unload a Component Object Model (COM) add-in. If you are not a developer, you generally will not need to load or unload a COM add-in because most COM add-ins include an installation program that loads or unloads it for you.

Load a COM add-in

1. On the Tools menu, click Trust Center, and then click Add-ins.

2. In the Manage list, click COM Add-ins, and then click Go.

3. Select the check box next to the add-in name, and then click OK.

   If the add-in you want is not in the Add-ins available list, click Add, locate the add-in, and then click OK.

Unload a COM add-in

1. On the Tools menu, click Trust Center, and then click Add-ins.

2. In the Manage list, click COM Add-ins, and then click Go.

3. Do one of the following:

   • To remove an add-in from memory but keep its name in the list, clear the check box next to the add-in name.

   • To remove an add-in from the list and from the registry, select its name and then click Remove.

     Note: Unloading an add-in doesn't remove the add-in file from your computer. It just removes the add-in from memory and from the registry.
