Suave isn't signed with a paid Microsoft certificate yet, so Windows warns you the first time.
- "Windows protected your PC": click More info, then Run anyway.
- Windows 11, "Smart App Control blocked an app that may be unsafe": Smart App Control can't make an exception for one app. To install Suave, open Windows Security › App & browser control › Smart App Control settings and choose Off. On an up-to-date Windows 11, you can turn it back on there later.
