ERROR 1919 Configuring ODBC

I am using Windows VISTA 64 bit Home Edition
I am using Microsoft Office Professional 2003 software

I am receiving the following error message:

'Error 1919 configuring ODBC Data Source
Component not found in registry.'

I research this error online and found instructions from Microsoft support
to help correct this problem
One of the instructions was to export two .reg files from another computer
on my network where the software was working and then import them to the
computer that needed to be fixed.
I did this, but it was not successful because on one of the ODBC files I
exported, I received the following error message when I attempted to import
it:

cannot import ODBC2.reg . not all data was successfully written to the
registry. Some keys are open by the sytem or other processes.
The folder I exported this from in the registry was
HKEY_LOCAL_MACHINE/SOFTWARE/ODBC

I attempted to do this in Safe Mode and was not successful with importing
from there as well. I received the same error message

Thank you in advance for your support and suggestions,
