LoopScore

Download & Install

Download the installer from the link above.
Double-click loopscore-1.0.0 Setup to run the installer.
Windows may show a SmartScreen prompt ("Windows protected your PC") because the app is unsigned. Click More info, then Run anyway.
The installer runs silently and finishes in a few seconds. LoopScore will launch automatically and a shortcut will be added to your Start Menu.

LoopScore will ask you to choose a base folder for your .lscz composition files. This can be changed later in Settings.

Open Settings → Apps (Windows 11) or Control Panel → Programs and Features (Windows 10), find loopscore, and click Uninstall.
Or run: %LocalAppData%\loopscore\Update.exe --uninstall
Your .lscz files are not deleted.

Download the application from the link above.
Unzip the file and drag LoopScore into your Applications folder.
Bypassing Gatekeeper: Because LoopScore is not yet signed, macOS will block it on first launch. To open it:
- Right-click (or Control-click) the LoopScore icon in Applications.
- Select New Terminal at Folder from the context menu.
- Type xattr -rd com.apple.quarantine . in the Terminal window and press Enter to run.
- Return to the Applications folder and click the LoopScore icon to open.
- You only need to do this once. Future launches work normally.
On first launch, LoopScore will ask you to choose a base folder for your .lscz composition files.
