# Action Wizard

Currently, InstallShield supports calling a DLL function or launching an EXE (a “custom action”) from within one or more of a setup's sequences.

Double-click the Action Wizard item in the tree view to launch the wizard. Using the Action wizard, you can create a custom action and specify where you want it to be executed in the Installation, Advertisement, or Administration sequence. You must also use the Action wizard to modify an existing custom action.
