>>It does make sense in our case to have local data and some other stuff in ProgramData folder. The local data is only a backup, the main database is in SQL Server.
Naomi, have you considered %appdata% in that case? Then the "backup" is per user with no interference or UAC issues, even if you end up running under TS.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
