The Microsoft Store version of FxSound (version **1.1.16.0** ) includes a separate app called “Check for FxSound Updates”. If I run this app (normal or elevated credentials) on Windows 11 Enterprise it does find an update (74.37 Mb) and downloads it. However it fails to install, with the error “Digital signature mismatch. Please contact support”.

Please fix this update.

Thanks for a great app.
