Backup Anywhere software will not install

I have searched and not come up with anything in WD’s site (including here) regarding this. If I missed it  I’d appreciate being pointed to it.

I have the MyBook World II 2T network drive.

I’m trying to install the Backup Anywhere software.  FIrst I tried the CD.  After clicking the Backup Anywhere button, nothing seems to happen.  Documentations says this could take a couple of minutes before the next screen appears.  I’ve given it 15 minutes.  I also downloaded the latest version of this software from WD’s site.  After clicking on the language selection (English), again nothing seems to happen. 

System is XP.

Any suggestions?
