John Fultz has already answered my question: http://groups.google.ru/group/comp.soft-sys.math.mathematica/tree/browse_frm/thread/3323f4620fd5ecae/2f967bd3fdb83c1f?rnum=1&_done=%2Fgroup%2Fcomp.soft-sys.math.mathematica%2Fbrowse_frm%2Fthread%2F3323f4620fd5ecae%3F#doc_b08ead07171bd17e I need Version 5.2 for having a possibility to run old programs without difficulties and because in some cases it takes less memory when loading data and it may be critical. See for example this thread: http://groups.google.ru/group/comp.soft-sys.math.mathematica/tree/browse_frm/thread/7f7c9e8baf1d63b6/1f5a8e4a1ef8c9a5?rnum=1&_done=%2Fgroup%2Fcomp.soft-sys.math.mathematica%2Fbrowse_frm%2Fthread%2F7f7c9e8baf1d63b6%2F8a9f3c97fb0f16e9%3F#doc_8a9f3c97fb0f16e9
