How far did you get with installing the wallet? If your talking about extracting the blockindex, you can just extract it to any folder thats convenient for you then right click and select copy, go to the
the newyorkc folder in appdata>roaming and right click in the folder and select paste.
 Or alternatively from the window where you extracted the files click and select the files and drag the files to the open  newyorkc folder and click replace files.
