Our adobe is working on and off. I have difficulty converting an adobe excel file to PDF and then saving it to desktop. Sometimes it works, sometimes I have to play around with system.
I can scan a document and create PDF and save it to desktop but not an excel. Not sure why.
Please tell the OS and Acrobat version you work on.
Do you experience any error message or any other behavior?
What happens when you try to convert an excel to a PDF?
Try to updated your Acrobat to the latest patch and then see if that helps.
