senang saja kalo ada iilustrator just run the program then open la file pdf tuh or place pdf file tuh...kalo multiple pages siap dia tunjuk & suruh pilih page mana you nak bukak
tapi soalannya you ada install program illustrator ka in the first place??
wait seminit...why do you want to open pdf file in illustrator???mau edit ka???bukan ka senang bukak pdf file palai acrobat reader saja???
