I have question regarding Integrating FOD's into ISO. For LTSC 1809, I have installed Croatian and Japanese Language Packs through Windows Update and disabled it afterwards. I would like to re do my ISO and integrate said Language Packs in it but I am unable to find them. After checking thread about adding Language Packs to ISO by Clanger, I tried integrating them but it always gives error when integrating and then it is left out of ISO. Is it possible to extract them and integrate to fresh ISO or no?
