I'm sorry you hit this.
AFAIK this bug is triggered if you (knowingly or not) try to use the COM
interface but haven't got a Java JRE (or Java JDK) installed with the same
bit width (i.e., 32 bit or 64 bit) as Octave.
(FYI on Windows you can have both 32 bit and 64 bit Java JREs installed side
Anyway this was fixed in the io package some time ago. One of these days
I'll make a new io package release with a.o., this bug fix, but I haven't
found the time yet.
So the easiest workaround at this time is to install a proper Java JRE;
another way out is using the OCT interface, as suggested by Andreas (but yes
it is slower than COM).
