SPSS 11.x can be installed on CXOffice 4.2.0, the installation still freezes at the end, but after killing the installation process SPSS can be started. The file opening dialog issue is fixed on 4.2.0, at least on my configuration. Basic functionality works, e.g. most statistical tests that I tried. Output of graphs, etc., does not work yet for me.
Good to see this progress compared to 4.1.0 :).
