What you need can be done by using an advertised shortcut. Here are the steps:
- you add the files in the "Files and Folders" page and the registry entries in the "Registry" page
- in the "Install Parameters" page make sure that the "Installation Type" combo is set to "Per-machine if user is administrator, per-user otherwise"
- in the "Files and Folders" page create a shortcut to the main EXE of your application in the "Application Shortcut Folder" directory
- in the "Edit Shortcut Properties" dialog check the "Advertised Shortcut" option
- in the "Organization" page make sure that all the components are under the same feature
Now, when an user (other than the one that installed the application) uses the shortcut, the feature which contains it will be installed for him (the registry entries will be created under HKEY_CURRENT_USER).
