The trick (you have to have a trick to read your OWN files on Windows 7 even though you paid $$$ for ....) anyways the trick is to copy ntbackup.exe program from another machine:
The files you'll need to copy are
ntbackup.chm
ntbackup.exe
ntbackup.hlp
ntmsapi.dll
vssapi.dll
the chm and hlp are nice to have and I don't think they are required.
copy anywhere on your new system and just start ntbackup.exe you may get a warning saying that the program cannot connect to the Removable Storage service which you can ignore and proceed to read your BKF files.
What were they thinking?
