There are several components that require Administrator privileges to install. In addition, the MDAC install must modify the system registry.

Some components that require Administrator privileges to install are:

OLE Automation (Oleaut32.dll, Olepro32.dll, Asycfilt.dll, and Stdole2.tlb), which is required by MDAC components including OLE DB, ADO, and RDS.
Visual C++ Run Time Library (Msvcrt.dll) might also require administrator privileges to update. Without Administrator privileges, you might see the following error:
