Monitoring an installed application

I have an application I've installed on a laptop. I want this application on my new laptop but now longer have the application. (lost the CD). How could I copy the application? Given, I'd copy the directory and what was placed in the registry, but how do I know all the files and DLLs that were placed in other directories. Such as, Windows\System32, etc.?

My OS is WinXP Pro. Does anyone have such a utility?

Thank you in advance.
