Uma Viewer (2)

⚠️ If you see "Failed to load il2cpp" or the app cannot start on Windows, it may be blocked by Windows Smart App Control.

If it fails, turn off Smart App Control:

Windows Security → App & browser control → Smart App Control settings → Off

This issue is caused by Windows blocking unsigned builds. The program should start normally after moving it to a local folder or disabling Smart App Control.

Unity application that makes it easy to view assets from Uma Musume: Pretty Derby.
