... it seems this is not due to the io package or MS-Excel 97, but 
rather due to Windows issues. I'm guessing you have Windows 7, don't 
you? (BTW is it 32 or 64 bit?)

See here for similar problems:

It seems Microsoft silently changed something which broke ActiveX / COM 
support. Not only for Octave, but for that matter also for Matlab. I 
think TMW has fixed this now, but the (octave-forge) windows package 
might need an update as well.

Currently your only resort is Java based spreadsheet I/O.
