Eshtaol,
Have you confirmed that double clicking on a .pdf file from within a file explorer works to open the file?
If not, uninstall/reinstall Acrobat Reader DC to reset the system defaults for .pdf and Acrobat files.
If a .pdf attachment will open using the "Open" button but not by double clicking the filename disable the "Turn off attachment preview by default in the attachment view" option located in Tools > Options > Incoming Mail >Message reader.
If you can open .pdf files with a double click from within a file explorer AND have ruled out the attachment preview setting as the source of the problem then...- Within Pegasus Mail go to Tools > Options > Incoming Mail > Content viewers
- Delete the entry associated with ".pdf".
- Delete the entry associated with "Acrobat" if one exists.
- Restart Pegasus Mail
- Try opening a .pdf attachment
If that doesn't work,...
- Within Pegasus Mail go to Tools > Options > Incoming Mail > Content viewers
- Click the "Add" button,
- Tick the "Filename extension" option then enter ".pdf" in the "Matches this" box (no quotes).
- Leave the action set to "Let Windows choose..."
- Click OK
- Click the "Add button again
- Tick the "Attachment type information" option then select "Acrobat" from the drop down list available for the "Matches this" box
- Leave the action set to "Let Windows choose..."
- Click OK
- Click OK again to close the Preferences and Settings window.
- Restart Pegasus Mail
- Try opening a .pdf attachment
If that still doesn't work...
- Within Pegasus Mail go to Tools > Options > Incoming Mail > Content viewers
- Select the .pdf entry then click the "Edit" button. In the action section tick the "Run this program" option the click the "Browse" button and navigate to the Acrobat Reader DC installation files (likely 'C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader'). Select the Acrord32.exe file. Click the Open button.
- Click OK
- Select the "Acrobat" entry then click the "Edit" button. Do the exact same thing.
- Click OK until you are out of the Preferences and Settings window.
- Restart Pegasus Mail
- Try opening a .pdf attachment
That is my brain dump on the subject.
