Error using MS Word. Make sure MS Word is installed and running correctly

This is because Word is configured to open in Reading Mode.  Reading mode does not allow for merging of data.  To solve this,

1.  Open a Word document.

2.  Open Word options from the File toolbar.

3. On the bottom of the General tab uncheck the box that says “Open e-mail attachments and other uneditable files in reading view.” This will prevent Word from opening in read only view, therefore the data will merge.
