Access Violation in module IDODBC32.DLL

Hi, it's Roberto from Italy

I made an application with Delphi 4, that uses an ACCESS Database via BDE
and an ODBC alias. Since there everything is OK.

I then installed Microsoft Data Access Components 2.1 (MDAC_TYP.EXE) and
some tables are no longer accessible from the application. The error is
Access Violation in module IDODBC32.DLL

Can anybody help me???

Thank you in advance!!!
