I am trying to create an application that will update a license file
for one of my applications. I need to delete the old file and replace
it with the new one.

I know how to do both, but my question is, is there a specific order
that ZEN uses on the Distribution Options/Applications file screen? Do
I list the file to delete first then list the one that I want to copy

I am restricted in my ability to test, as I do now have access to this
specific software. Any help would be great.
