The international language versions can indeed only be updated to 1.68 (officially, at least). But there is a trick to patch them up to 1.69.
Replace the international version of dialog.tlk with the english version from 1.68, then apply the 1.69 critical rebuild patch (in my case, a year ago, even the normal update procedure worked), afterwards, replace the dialog.tlk with the international one. On nwvault, there is at least a german 1.69 dialog[f].tlk for download.
This should work for all languages.
