When trying to update to 10.1.2 it asks for a cd-rom but as I downloaded from the internet I do not have it. I tried downloading 10.1.2 from the internet but received the same message. It also referenced a file from the disk but when I searched my computer for the file it doesn't exist.
Could you give us some minimun information? We don`'t even know if you are in Mac or Win, or what program you are talking about.
Also please give the exact and full message you are getting.
