I think Kai is likely right.  I ran into this problem on a managed
machine at work.  Security policy rollout included disallowing
executables from the Temp space through Group Policy, which included
the compiling Octave does for some packages.

What I did was make a C:\Octave\Temp folder, and then at the start of
every Octave session I execute:

setenv('tmpdir','c:\Programs\Octave\Temp\')

(i added that line to the .octaverc file located at the base of my
user profile folder)

give that a try. if it works you know that's the problem.
