This the kind of thing that depends on your customers. Sometimes too much choice is a bad thing. If I installed a new product and it said "do you want to start some service?" my reaction would be "how the hell would I know and why should I care?" Just start the darn thing! It's potentially up there with things like wanting to give the installing user multiple browse dialogs, one for the application folder, another for some database, another for some other files, etc etc. I'm on a soapbox here, but when people wonder why installation can be so complicated the short answer is that sometimes we go out of our way to make them that way.
