Press F11 on your keyboard. This exits full-screen mode, which hides the menu bar. If that doesn't work, try F9 or F10 (depending on your version).
Outdated versions may have UI bugs. Update to the latest version from within Nitro (Help → Check for Updates) or from the official website.
Here’s a post you can use for a forum, social media, or support community: Nitro Pro Menu Bar Missing – How to Fix It
Press Ctrl + F8 to toggle the Ribbon (menu bar) on/off in newer versions of Nitro Pro.
If nothing works, go to Control Panel > Programs and Features , select Nitro Pro, and choose Repair . Still missing? Uninstall and reinstall the latest version from your Nitro account.
Go to the View tab (if you can access it via keyboard shortcuts or right-clicking the toolbar area) → Reset Workspace or Reset Toolbars .
If the menu bar (File, Edit, View, etc.) has disappeared in Nitro Pro, don't worry — it’s usually easy to bring back. Here’s what you can try:
Close the application completely, then reopen it. Sometimes the interface just glitches.
If all else fails, contact Nitro Support — they’re usually quick to respond.
Hope this helps! Let me know if you’re using a specific version (e.g., Nitro Pro 12, 13, or 14).
