There are 2 files you probably want:
Octave3.6.4_gcc4.6.2_20130408.7z  (base program)
Octave3.6.4_gcc4.6.2_pkgs_20130402.7z (packages / extra functionality)

Yesterday, I downloaded and installed the base program indicated above on a
Pentium D 3.4GHz machine running 32-bit XP Pro SP3.  It has the following
issues:

1) It takes 30 seconds to give me the command prompt every time I click the
provided link to start the program, and

2) It takes 90 seconds to load a 2500x2500 element 12MB text file into a
matrix; SciLab takes less than 2 seconds to load the exact same text file.

Other than that it appears to work correctly, although the only script I
have run on it so far is this:

tic; d = load('d.dat'); toc

tic; N = load('N.dat'); toc

tic; r = N \ d; toc

tic; Ns = sparse(N); toc

tic; rs = Ns \ d; toc
