It depends how you're giving your client the application. If it's already on the system you're just giving them access to it then you could have a secret file, which is deleted upon installation - and can't be reinstalled unless the file is there.

If it's on a CD then you'd need some kind of CD Key... which :S I'm not sure it's possible to make it work with out a connection to the internet during installation.

Like... connect to internet and must have their key match a key off a site you host, if it's not on there then it doesn't continue and says already been installed on another system.

Other than those, I can't think of many other ways around the problem.

Hope it helps, Geoff.
