You can download the latest version of MuseHub from the main website, www.musehub.com
macOS:
Double click the "MuseHub.dmg" file to mount the disk image, then drag and drop the Hub icon into your Applications folder. Click "Yes" when macOS asks if you'd like to open the application.
Important Note: You must run MuseHub from your Applications folder.
To install and manage applications, plugins and Muse Sounds, MuseHub requires your permission.
When prompted, be sure to click "allow" to grant MuseHub permission to update and manage content on your device.
You can also toggle this setting at any time from the macOS System Settings. Go to System Settings, then search for "Login Items". Within the "Allow in the Background" section, find the MuseHub toggle, and make sure it's switched on.
If you disable this toggle, you may find the MuseHub doesn't operate correctly.
Windows:
Double Click the "MuseHub.exe" file. The Hub will perform a short first time setup as it checks for required frameworks. Once it's running, you can find MuseHub in your Windows system tray. If you have many items running in your tray, you may need to click the disclosure arrow to show the MuseHub icon.
If the app is not running for some reason, you can launch it from the Start menu.
