Software and installation

After connecting my new external hard drive the computer found it almost immediately and reported the drive as ready to use.  However, when I opened the drive the first time, using Control Panel, there was no software to be found.  After that time I did find software on the WD site that has been downloaded and stored on the external hard drive.  There is one utility, however, that when I try to run reports that a file or program the utility needs can not be found.  Any suggestions?

I found in another post that you have a WD Elements, there is no software bundled with it, you can use it to drag and drop files to it or with the backup software of your preference.
