Access 97 Delphi 4 , Indexerror


I use D4 and Access97 Database. My Application use ODBC to connect to
the Database.

On Maschine A, B, C , X, Y and D is runs fine and correct. On other PC's
(same Windows Version, same Modell !) I get a "Indexerror" when my
Application is up, and the first Query runs.

Can anyone tell me why ??? what can I do ? I can' t find any errors.

Tip: I have Installed my Application with the same Disks (from IS Express)
on all the machines.
