a database problem (Jet 4.0 Driver??)


I have a database application built in Delphi7 that uses MS Access via ADO components (Jet 4.0 driver)

In my application, I have a query that brings a dataset (join of a number of tables)

When I try to change a field on the DBGrid that displays this resulting dataset:

1) This change is reflected to the Access file, when the application
is run on the compiled machine

2) But it is not reflected to the Access file on some
other machines (but not all of them).

What may be the reason? If there is something wrong in the code, the result must be the same everywhere. Or am i wrong?

Is it about the Jet driver or MDAC? If it is, what should i also install
along with the application itself?

Thanx in advance.
