Hello. My name is ***** ***** I will be assisting you today.
What version of Microsoft Office do you have? Do you know when this error started happening? Did Microsoft Office come pre installed with the PC or do you have CDs if we need to reinstall it?
I should have said, do you have a product key for Microsoft Office, as we can always download the install files.
Checking in to see if you still need help with this issue, if so please reply at your convenience.
