For example, you need to check whether the user has JET 4.0 or ACE 12.0 in the system.

    Generally, these are OLE DB providers and their search is performed using OleDbEnumerator .

     using System.Data.OleDb; . . . OleDbEnumerator enumerator = new OleDbEnumerator(); DataRow[] foundRows = enumerator.GetElements().Select("SOURCES_DESCRIPTION = 'описание провайдера'"); if (foundRows.Length > 0) { /*OLE DB провайдер установлен! Всё в порядке!*/ } else { /*OLE DB провайдер не установлен!*/ }

    Alternatively, you can search by system name:

     DataRow[] foundRows = enumerator.GetElements().Select("SOURCES_NAME = 'имя провайдера'");

    Only here descriptions and system names of providers for Access, I can not tell you right away.
