Configuration

The setting for preflight path is in MCU, Under "preferences" > "System Settings" then under "Privilege Manager for Sudo" there is a section called "Software & Licenses"

This will have a path set likely ending in default. MCU always looks for whatever is set there, then "sudo_plugin" then the architecture.
So if the path is set to
c:\default

Then the files need to be in the following path for 32 bit RHEL as an example
c:\default\sudo_plugin\linux-intel
