+Yes, Ghost Proxifier Pro is a paid, licensed product. Non-Pro users cannot drag and drop shortcuts or exe programs for direct injection — they may only use the manual selection dialog to choose a program's shortcut or exe, with a limit of 3 applications. Each injection session is capped at 2 hours, after which a restart is required to continue. Pro paid users have no such restrictions: drag and drop as many applications as you want with no per-session time limit. For Pro pricing, please refer to the official website or consult the developer through the community group.

+Both Pro and non-Pro users have full access to automatic process tree injection tracking, traffic visualization, DNS anti-poisoning, and other features.
