How to transfer files to new computer using My Passport external hard-drive?

I have a similar situation - but I had to re-install Windows 7.  I installed the WD anywhere backup software from my external Passport Elite and am trying to restore all my backed up files.

I keep gettin the message that the operating system is not supported.  “WD Anywhere Restore cannot be run under this version of Windows.”  I know that’s not true because I used it before I re-installed W7.

What am I doing wrong?  Do I have to create all the folders - shouldn’t “restore” also restore all the folders?

Any guidance would be appreciated.
