It's not out for business yet. Kaseya can't do anything until it's released. The CEO of Malwarebytes said it would be available "towards the end of this year"

I look forward to it. The scan times seem much quicker with the new version.

I was always under the impression the malwarebyte version through Kaseya was a modified Pro (which was renamed to Premium in version 2) and not Business. I look forward to the update either way when it comes through.
