Which version of MS Office do you have installed and have you installed the latest Service Pack for that version?
Using Google, I found the suggestion below from THIS LINK:
This error is caused by the "Speech and Handwriting Recognition" feature of MS Office. You can turn this feature off by going to the Add/Remove Programs applet in Control Panel. Click on the entry for MS Office and then on "Change". Browse to "Office Shared Features," "Alternative User Input," and make Speech and Handwriting Recognition (both) "Not available" from the drop-down box.
Hope this helps.
