Freedome does not launch on my Mac

Freedome VPN does not launch on my Mac even though I click Freedome icon on my Application folder. 

There is no error message showing up. 

 

I already tried these:

1. Delete Freedome app with relevant folders/files (https://community.f-secure.com/t5/F-Secure/Freedome-won-t-open-after/td-p/74895)

2. Reinstall the latest app from the website (https://www.f-secure.com/en/web/home_global/freedome-download)

 

Mac version is: macOS High Sierra ver. 10.13.3

Macbook Pro Late 2016 15 inch

 

Please let me know if there is anything I can do.
