If you get a Windows Smart Screen alert, click on More info, this will let you run the installer anyway. JJazzLab is NOT a malware!

Because version 2.3 is brand new, Windows security servers don’t have enough statistics to evaluate its “security reputation”. Alert will disappear soon, once enough people have run the software.
