Upgrading Windows 2003 Standard to Windows 2003 Enterprise

When trying to upgrade my Windows 2003 Standard Edition DC to Windows 2003 Enterprise Edition, I get the error that the acpiec.sys file is corrupted. Press any key to continue.

When I hit enter, I get the error that the setup failed, press any key to restart the system.

I need to upgrade the server to make more ram available in the OS.

What can I do to successfully upgrade the OS?
