I cannot set conversion settings for Driver, what should I do?

Issue

Conversion settings appears blank and unable to set conversion settings for Driver.

Description

If Driver's conversion task fails, it would cause configuration file path error in the registry, making the watermark and encryption settings blank.

Solution

Close Driver and delete the following,

HKEY_CURRENT_USER\Software\Zeon\Gaaiho\Gaaiho PDF in registry, then restart Driver.

Reminder: you may access the registry by entering "regedit" in the run box or search box
