To achieve this, you only need to:
-Add the PDFE shortcut to the startup folder, you can get access to this folder from the start menu.
or
-Add a new entry into the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run, pointing to where you have PDFE installed.
To enable the automatic startup of the webserver you just need to enable the option "Autostart Web Server", in Edit>Preferences>General, or add the
-ws command line switch to the shortcut parameters.
You can also set the "Minimize to tray" and the "Start Minimized" options, or the respective
-mt and
-sm command line switches. This way, PDFE starts minimized with the icon positioned in the system tray.
Example of shortcut location using the command line switches:
"C:\Program Files\PDF Explorer\PDFExplorer.exe" -ws -sm -mt
