As mentioned earlier I have 2 OS M$ 2000 and 98se in 2 separate partion C&D , I've all my programs installed (messenger ,office)installed in 2000 , now I want to use these in 98 too, is there any way I can do this with out having to reinstall them . I mean to re -install is one more time and resource consuming head ach is there any way I can do this, you know registry tweaks and stuff like that .....???
