Important Note: Starting from version 6, "Right PDF" becomes the official name in place of "Gaaiho".
Conversion settings appears blank and unable to set conversion settings for Converter/ Driver.
If Converter/ Driver's conversion task fails, it would cause configuration file path error in the registry, making the watermark and encryption settings blank.
Close Converter/ Driver and delete the following,
HKEY_CURRENT_USER\Software\Zeon\Right PDF (Gaaiho)\PDF Driver (Gaaiho PDF) in registry, then restart Converter/ Driver.
Reminder: you may access the registry by entering "regedit" in the run box or search box
