No Install!

Totally lost my HDD (1TB Seag on a 2012 27"iMac). Replaced the HDD and added a 250G Samsung SSD Didn't have a complete backup so it's basically a complete new machine.
For some reason Little Snitch 3.3, one of the very first appsI install, will not install. It goes thru the motions up to the actual installing of files and then tells me "installation failed, see log"
The log tells me this: (which I'm afraid means zero to me)
