Why Msjetoledb40.dll is missing in Windows 2008 core - 32 bit and R2 as well?

Question

Hello,

I am working on Windows 2008 core R2 and 32 bit. While running application in which I am trying to connect to .mdb file by ADODB connection and using provider as 'Microsoft Jet Provider 4.0' . To get the connection done Msjetoldb40.dll is necessary. But it is not present in Windows 2008 core R2 and 32-bit ( which is of only command prompt).

Is there any reason that Microsoft has moved this dll from system32 folder.
