Is it possible for all PDF e-mail attachments to be opened by Acrobat instead of Adobe Reader?
Yes, you can configure your computer to open PDFs in Acrobat instead of Reader if both these programs are installed on your Windows computer. Simply go to any folder and select Tools > Folder Options from the menu bar. From the Folder Options dialog, select the File Types tab. Go to PDF - where it says “opens with,” change it from Reader to Acrobat.
