Privilege Violation (10004) error on attempted launch

Trying to install TotalFinder 1.3.2 on Sierra 10.12.6 and got a privilege violation (10004) on launch.

Anyone know why and a workaround?

DuckDuckGo searching returned nothing that I understood.
TIA.

I wonder why you decided to try installing TotalFinder 1.3.2. That is very old version released for Snow Leopard several years before Sierra existed.

You should install latest version:

btw. there is a reason why you should keep TotalFinder updated to latest version suitable for your system:
