AventailConnect-OSX64-10-7-2 Cannot Be Opened with iOS 10.12.4

Hi Community -

I stalled AventailConnect-OSX64-10-7-2 on my Mac (iOS Sierra). The software was installed successfully, but when I open it, I get this error:

Anyone has any suggestion on how to trouble shoot? I also have Sonicwall installed, but Sonicwall is causing issue with one of my vpn connect, and I was suggested to install Aventail instead.

Thanks in advance!
