i uninstalled it and then installed office 2007 that is worked good with dashboard 4.1 as others said
but no result ,
i tried then another source but there was an error INS 140 code valid after searching i used patch called iskeyvalid.exe and replaced it by origin files then it worked
but after installation it requested keycode again and with the same key that i used in installation and accepted after replacing the patch , it say that it's invalid again
please , give me any advice
