Good evening to you all. Pardon my crappy english... The problem is as shown below: I performed a clean Win XP install using a slipstreamed, custom made DVD. Everything went well, except for the fact that I can't change the language options for non-unicode programs (Control Panel > Regional Settings > Advanced). Every time I try changing the option to Greek, I get the message Setup was unable to install the chosen locale. Please contact your system administrator ...meaning me? Anyway, I've tried everything but re-formatting... The user is indeed an administrator. Any ideas? THX a lot
