The Installation failed

macOS Mojave Ver 10.14.6
Mac Pro (Mid 2010)
Processor 3.46 GHz 6-Core Intel Xeon
Memory 64 GB 1333 MHz DDR3
More than enough storage

I was excited about spending $300+ dollars until I was met with an error as the progress bar reaches the “Validating Packages” section. I’ve adjusted the permissions of the installer file to read & write for the system and that didn’t solve the issue.

I’m also aware that sometimes going to Settings>Security & Privacy>General allows us to manually allow a app to be installed, but Envy 2 doesn’t show up there.

I’m a bit at a loss, as I happily own two other Cargo Cult products, but there doesn’t seem to be any issue identical to mine so I could address the issue on my own.

Hoping an admin or someone else can offer solutions. I’m in the middle of a project and need this working asap.

Sorry, it’s not clear exactly what the problem is.
Are you saying the installer fails to install the products?

Can you please take a screenshot of any error messages and send to support at the cargo cult dot nz.
Cheers
Justin
