1033 is LANG_ENGLISH. 1045 is LANG_POLISH. I suspect your language settings aren't getting interpreted correctly. What's the LANG environment variable set to?
Actually I have unset LANG/LC_ALL, with Polish locale it works fine, but why it is based on locale, not on registry entries, etc?
I think it is possible to install Polish Power Point Viewer in English Windows (I can check it on Monday)
