Download and run KotonStudioSetup-1.4.0.1.exe.
It installs for your user account — no administrator rights required.
On first launch, Koton Studio offers to download MuseScore's SoundFont (.sf2) automatically to enable audio — or point to your own.
Later updates install automatically at startup.

ℹ The sound bank (.sf2) is not bundled (several hundred MB). Koton Studio can download one, or use e.g. MuseScore_General.sf2.
