[Composer] Can't install the package via ARD

[Mattias Hedman]

Hello all!
I've just made a package with Composer on a Intel Mac Mini (My dev machine).
The package is a .pkg and cannot be installed via ARD, I can install it
"local".

What have I done wrong this time?
This is the first time I get this error.

Sincerly,
Mattias Hedman
