Well... I copied the files from the Language pack to the Office CD without overwriting existing directories and files, but when i start the /admin option, i get a window that lets me select between the office and the language pack. (BTW, the language pack has 3 options: office, project, visio). I created the MST file with the support for the second language but when the CD starts i have to choose what i want to install. I want to make it totaly silent. Any thoughts? Thanks
