there's not that big a difference between the laptop and the pc itself. they all have a bios, processor, usb ports, and all that. if you tried to copy the entire drive over you'd have mixed results whether you did it pc to pc, or laptop to pc. (or any other way). most of the time it will simply see new drivers and keep installing them and rebooting till you're done. not really recommended but you can always transfer it over *then* install windows on top of itself and hope. if it flakes out be prepared to format and start over.
but as was pointed out early on - install programs do so much more than copy files.
look in the folder itself to see what's there and if you see a "setup.inf" file then you can open it up and look at all the reg changes it makes during the install and where it places all the files. you could use that as a guide to ensure you copy things over properly and to the right places, but even then you'd have to export the reg keys and import them to the new machine - which is easier than doing it manually.
if you registered the programs, then do as someone else suggested, go to their site and ask for a replacement cd. if you didn't, you may be SOL.
