Please help... Hard drive crashed and now need to restore but WD MyBook won't install

My Xp drive died and I have a new drive with Windows 7 64-bit installed.  Can browse my 1Tb MyBook, but can’t get the software to install to start recovery.  Lost everything, photos, contacts, music.  Installation gets to ‘preparing’ then never goes any further.  Have tried to install Backup, Memeo, even Google Desktop, it just hangs there.  Any ideas…  I need to know how to recover these files.  Am running the Data Lifeguard Tools Extended test, but the drive appears to be fine.  Thanks for your help!

Same problem. Even Advanced Disk Recovery cannot recover the files.

Any suggestions?
