A couple of days ago, I started getting this error message

Word cannot start the converter mswrd632.wpc

Can anyone tell me what this is?

Sometimes it will pop up twice, sometimes 3 times.

I did a search on this phrase and found articles on Lotus Notes and
Mail Merge. I have never used Notes. I have never used Mail Merge on
this PC.

I'm running Office 2007 on Win XP. I believe I have all the latest
updates.
