⚠️ Important: Windows SmartScreen Notice
Since HappyNote is a new application and we don't yet have an expensive code signing certificate, Windows may show a security warning. This is completely normal for new software.
How to proceed safely:
- Click "More info" on the blue screen
- Click "Run anyway" to continue installation
- Windows may ask for administrator permissions - this is normal
Why this happens: Microsoft requires established reputation or expensive certificates for new apps. We're building that reputation and will eliminate this warning soon!
