Running PERFLIGHT with Elevated Permissions (Administrator)

If you're switching from MSFS Addon Linker to PERFLIGHT, you can quickly import your existing library folders, location data, and presets in just a few clicks. This migration preserves your addon organization so you don't have to start from scratch.

Importing from MSFS Addon Linker

PERFLIGHT gives you full control over how your addons are displayed and organized. Taking a few minutes to edit your addon details - especially the Source field - will pay off as we add new features that leverage this data.

Editing Addons in PERFLIGHT

PERFLIGHT uses two different systems for organizing your addons: Libraries and Sets. Understanding the difference between them is key to getting the most out of the app.

Overview of Libraries vs Sets

The Pre-Flight Checklist gives you a personalized, step-by-step workflow to follow before every flight. Build it once with the steps that matter to you, then run through it each time to sync your flight plan, launch your tools, activate your addons, and start the simulator -- all from one place.

Pre-Flight Checklist

Flight Services is your launch pad for all the external tools and websites you use alongside Microsoft Flight Simulator. Configure your favorite apps and URLs once, then launch them with a single click from a clean grid view.

Categories control how your addons are grouped in the Library Manager. PERFLIGHT ships with four default categories, and you can create your own to organize addons however you like -- for example, splitting liveries into their own group or creating a category for your favorite freeware.

Creating Custom Categories

The settings gear menu in the Library Manager header gives you control over how addons are displayed, filtered, and scanned. Click the **gear icon** in the top-right corner of the Libraries page to open it.
