Don't think you have the correct file as i'm not sure what is the .msi

download a trial version of fabrication cam-duct 2023 version or older

that will save the default imperial and metric databases to you pc.

The default place they will be saved is -

(c:)windows\users\public\public documents\Autodesk\Fabrication2023

now open Cadmep and you should get a pop up request to load a configuration (screenshot)

select new

now point to where the downloaded database is (as above) and highlight the version folder (screenshot)

once you highlight the version hit select at the bottom

it should now appear in the opening list to load when you open up Cadmep as mine are in the screenshot

good luck
