Well, I was very excited to try out my shiny new UR-22C that I picked up yesterday, but everything has fallen apart at Step 1. 
I am trying to install TOOLS for UR-C (as per the manual) on my MacBook Pro (Mojave 10.14.6) but the installer throws the following error immediately:
The operation couldn’t be completed. (com.apple.installer.pagecontroller error -1.)
Looking at the logs for the Mac Installer, I find the following:
Nov 4 19:32:18 Orion Installer[1606]: PFPackage::packageWithURL - can’t instantiate package: /Users/***/Downloads/TOOLS_for_URC_V101_Mac 2/TOOLS for UR-C V1.0.1.pkg
Nov 4 19:32:18 Orion Installer[1606]: Invalid Distribution File/Package
I also tried to manually expand the .pkg from the command line, but I ran into the following problem:
~ $ pkgutil --expand ~/Downloads/TOOLS_for_URC_V101_Mac\ 2/TOOLS\ for\ UR-C\ V1.0.1.pkg ~/Downloads/tmp/
Problem extracting file from package: /Users/damonjmurray/Downloads/tmp//YamahaSteinbergUSBMIDIIcon.pkg/Payload
I’m stumped at this point and have no idea what to do. I’ve tried re-downloading the installer multiple times, restarting the machine, etc… Feels like I just gave away a heap of money and all I got in return was a useless brick.
Any suggestions or advice would be greatly appreciated.
