Even de documentatie door lezen en dan zie ik het volgende staan, het is mogelijk zolang je zelf actie onderneemt

If you'd like to make AP in a language other than English, here are the steps you need to take:
--------------------------------------------------------------------------------------------------------------------
1. You need to download all of the files that you want to be in your custom language from Microsoft.
2. You need to open all the axp files for the files you will be overwriting. Inside there you'll see something like this (I'll use Q322011.axp as an example):
"%AutoPatcherXP_Dir%\ProgFiles\Q322011_WXP_SP2_x86_ENU.exe" /q /z
You'll note on the file you downloaded it will be written like Q322011_WXP_SP2_x86_XXX.exe Now where the XXX is will be your specific language code. For example, English is ENU, German is DEU, etc. In each of these axp files you need to just take out the ENU and replace it with the country code you're using. So if you were converting to German, it would go from:
"%AutoPatcherXP_Dir%\ProgFiles\Q322011_WXP_SP2_x86_ENU.exe" /q /z
to
"%AutoPatcherXP_Dir%\ProgFiles\Q322011_WXP_SP2_x86_DEU.exe" /q /z
Then you'd just save it and go to the next. You don't need to change the name of the axp file or anything else. Just those three letters inside. On some files the custom language name of the file is the same, in that case you don't need to edit the axp file.
3. When you're all done with those, you'd need to open the ProgFiles directory. Delete out all the files you plan on replacing, and then copy in yours.
4. Finally, open the autopatcherxp.apdb file and where it says:
Language=English
Change it to your language, for example, if you were making a German install, you'd make it say:
Language=German
--------------------------------------------------------------------------------------------------------------------
That's it. Now that you've done that, when running the AutoPatcher, it will install your Language version of the updates, rather than the English Version. If you'd like to add extra updates, just follow the instructions on how to make a custom install.
Misschien een handige link om de updates te zoeken.
