error message on letter merge

Using a standing ACT template...when I try to do a mail merge I'm getting an error message that says - "Interface not Registered. (Exception from HRResult: 0x80040155) Then the merge completes and I have my merged data from the contact record in the letter. Anyhow - how do i resolve this?

Re: error message on letter merge

This is generally because a component of Word is not registered correctly. You could try the following which came from one of the Microsoft forums


Start, run, enter... type in the following command
