I think 7zFM.exe is't the right program to use.
For kmPackager, I use 7za.exe which is a line command for 7z, and it works.
I don't know if it's installed with 7z, look for 7z folders, and set the path to it.
Thanks very much JuJuland, Tried this but no go I am afraid. Wondering if the 'utils' macros need any extra actions to install. They are in there, lised in the GU
