Dear Grabben, I'm facing the same problem. I have integrated (twice), first selecting Ultimate x86 and adding all updates (x86) and PT language(x86), then selecting the altered WIM (with Ultimate PT Lang and Updates all x86) and choosing Ultimate X64 and adding all updates (x64) and PT language (x64). During my tests the Windows Ultimate x86 and x64 were installed without any errors, although the updates somehow weren’t installed (because Windows Update wanted to download all of them again). All other versions (when PT language was selected) stopped with and error couldn’t find language file. So I do have to integrate on each index (for all versions)? Right? What was your approach? Did you manage to add your language (Swedish) to all versions? x86 and x64? And what about "Starter" and "Home" editions? Thanks in advance, Best Regards, FJorgeR.
