Installing w/o Installer

Recently I got a new computer, and like an idiot, I moved all the program files onto the new computer without the installer applications. Most programs I just installed again on the new computer, but one, Microsoft Office specifically, took to long for me to download again.

I am now stuck with this folder with a crapload of .dll files, applications, text files and a whole lot of other shit.

Is there something that would help me put all of these files into their respective places?

btw I'm kinda a newb at computers

Copying the entire registry won't do you any good.
