I'm not sure where you have managed to get to or why you want the CD.
Since we do not use the windows operating system here we have never used the CD. What we do is open a browser (firefox in our case) put http://192.168.0.32 in the address bar, give the username as admin and we can then setup the NAS.
Before you can map anything you need to setup services and who can use them (example, CIFS (Samba), FTP Server and so on). The FTP server will allow you to use FileZilla to transfer anything from single files to the whole hard disk. To use CIFS and FTP it requires you to set up network shares (under account management). Once you have those setup the NAS should appear under network places in windows.
All of this information is in the manual even though they do rabbit on about the CD at the start - it isn't necessary.
