Thats a known issue with nsis in mxe-octave, mentioned in the index.html.
It also doesnt work with mxe unless you have built the 32 bit compiler.

GWL_USERDATA is a win32 define, which needs to change to GWLP_USERDATA 
and use SetWindowLongPtr instead of SetWindowLong.
There are a number of other similar issues as well.

nsis is only required for the install, so building a tarball disto is 
still possible.
