Reinstalling NAV on my rebuilt drive

I've swapped in a new larger drive and have reinstalled XP. First thing I want to do is reinstall NAV.

 

 

I don't know if I've still got the downloaded install EXE. but I have everything else, including NAV working on my old drive and various product keys / serial numbers. I'm not exactly sure what version I'm running but I've updated it in the last year.

 

With the right product key can I download NAV again to reinstall?
