Nothing in the system logs?

Needed by the client library. You should check that they are there
(msvcrt.dll and msvcp60.dll).

Are you sure it's not a permissions problem? Are users accessing the exe
locally? or from a network share? Have you attempted to run either of the
apps under the Administrator logon?

Also test that the correct client library is (1) available on the user's
local disk; (2) is in a path that is known to/available to the user and
(3) has the right name (gds32.dll by default unless you included a custom
ib_sessionXXX unit as the first item in the DPR uses clause).
