Compile error in hidden module autoexec is an error that comes up in word or excel sometimes. To fix this solution there is a certain codec u must download. This add on is available at http://www.adobe.com/products/acrobat/update.html. If that does not work there are a couple other things to try.one is to move the Pdfmaker.dot file and the Pdfmaker.xla file from the Office or Excel Startup folder
. to a different folder on your hard disk. If this does not work your guess is good as mine.
