im trying to reinstall office 2003 on a friends computer after i reformatted it and im having some trouble. i can get thru the cdkey and can choose what to install but during the installation it locks up on a cab file named w4561405.cab. i browse to the cd drive nothing. so i thought the cd might be screwed up so i made a copy nothing. well i thought ill rip the cd to my drive then install it over my network still locks up on that file. ive searched and search with no luck. anybody got any ideas? thanks
