Anyone here uses Boom2?

Hi everyone,

I recently got Boom2 on my Mac. When I tried to set up audio, it says "To use Boom2 volume booster, you need to download an optional Boom2 device." So, I went ahead and download the Boom2 device thingy or whatever it's called. And I got a zip file sitting in my Downloads folder. So I extracted the zip file, I got a pkg file. And I launch the installer. I followed the installer screen, entered my credentials, and click the "Install" button. The installer went well, until it got to some point, it throws me an error. It says, "The installer has failed." Maybe this doesn't work in High Sierra?

If anyone had use this software on High Sierra, could you help me with this?

Thank you. And sorry for my English.
