Install the app

Download

Download the installer for your platform from the website: the Windows installer (.exe, 64-bit) or the macOS installer (.dmg, Apple Silicon). The page always offers the latest release. The app needs a LED account with a licence — see Sign in.

Install on Windows

1. Download the Windows installer (.exe) from the download section of led-manager.com and double-click it.
2. If Windows protected your PC (Microsoft Defender SmartScreen) appears, click More info and then Run anyway. It shows because the installer is not yet signed with a Windows code-signing certificate.
3. Step through the short installer wizard:
   • License Agreement — read the LED Event Manager copyright and third-party notices and click I Agree; the app installs only after you accept them.
   • Choose the install folder — the app installs for the current user by default, so no administrator rights are needed. Pick another folder if you like; the installer asks for administrator rights only when that folder requires them.
   • Click Install and wait for the files to be copied.
   • Finish — Run LED Event Manager is checked by default; leave it checked to start the app right away, then click Finish.
4. A shortcut is added to the Start menu and the desktop.

NDI output needs no extra install on Windows: the installer ships the NDI runtime. A system-wide NDI install still works too — the app prefers the runtime that came with the installer and falls back to the system install.

To uninstall: Settings → Apps → Installed apps → LED Event Manager → Uninstall. Your projects stay in the data folder — see Where your projects are stored.

Install on macOS

1. Download the .dmg file from the download section of led-manager.com and double-click it.

2. The LED Event Manager copyright and third-party notices open: read them and click Agree to open the disk image (Disagree closes it).

3. Drag LED Event Manager into the Applications folder.

4. Open Applications and double-click LED Event Manager.

5. The first start is blocked with a message that Apple could not verify the app (the app is not notarised by Apple yet):

   • click Done (not Move to Trash);
   • open System Settings → Privacy & Security, scroll down, click Open Anyway next to "LED Event Manager" and confirm with your password or Touch ID.

   On macOS 14 and older it is enough to right-click the app → Open → Open.

6. From then on the app opens normally.

For NDI output on macOS, install the NDI Runtime (part of NDI Tools) first. More about NDI: ndi.video.

To uninstall: drag the app from Applications to the Bin. Your projects stay in the data folder.

Updates

The app checks for new versions by itself and asks before it installs anything — see Updates.
