I attempted to reinstall the Siebel CRM. I went through the process and 
got this message "Siebel e business applications require Microsoft ODBC 
Access Driver at version 4.0.3711.8 In checking your installation none 
was found. Can you please tell me how to find this driver and how to insatll it?
I tired going to Micrsofts site but I couldn't find it.
Thank you very much
Howard

Microsoft Data Access Components (MDAC) 2.8 contains core Data Access
components such as the Microsoft SQL Server OLE DB provider and ODBC
driver. This redistributable installer for the MDAC 2.8 release
installs the same Data Access components as Microsoft Windows Server
2003.
This release does not include Microsoft Jet, the Microsoft Jet OLE DB
Provider or ODBC driver, the Desktop Database ODBC Drivers, or the
Visual FoxPro ODBC Driver.
