Upgrading DLL's in Windows 2000

Hi,

I am wanting to update two DLL'd on a Windows 2000 Proffessional PC. The DLL's are MSADO15.DLL and MSADOR15.DLL. These two DLL's can be found at the following path C:\program files\common files\system\ado

I have a batch file that when executed from the DOS prompt, it renames the two old DLL's, copies on the new ones, then registers them both. This batch file works well on Windows 95,98, and NT 4 workstation. When the batch file is executed on a Windows 2000 Professional PC, as soon as you rename or delete one of these DLL's, Windows 2000 automatically creates a new DLL.

I need to be able to update the version of these to DLL's.

I have even tried writting a VB program tyhat uses these two DLL's, and getting the VB setup program to install and register them, but this does not seem to work either.

Anyone know how to update these two DLL's.
