I've never been able to figure out how to set up enough of the preliminary stuff for accounts to get Money to do anything but connect me to stockbrokers who want my money, so I still do my stuff in Excel - like 20 years ago.
Windows versions are language specific to an extent, although there's some latitude for choosing a language in Windows, in IE, and in some programs. Money probably takes it's setting from an Office setup, althought I don't have it on a machine to check that out.
If it's getting it from Windows, Start - Settings - Control Panel - Double-click "Regional and Language Options" - should let you change it.
If it's getting it from Office settings, changing it in Word (sort of the master office program) should change it for all Office programs. In Word, Tools - Language - Set Language should get you there.
If it's a Money specific setting, it's probably on the Tools button (if there is one).
