I have eliminated Adobe's additions to MS Office programs and they duly disappeared from all programs, except from Visio. I physically deleted the file C:\Program Files\Adobe\Acrobat 6.0\PDFMaker\Office\PDFMVisio.vsl, but now each time I start Visio, I get a warning: "Visio could not find this add-in or one of its files. This feature is not installed. Would you like to install it now?"

I haven't been able to find where the add-in definition resides. Can anyone help me get rid of the nagging warning?
