You want to copy the whole JMRI directory and contents and reload that in the new computer to a similar spot. On the old system the login name was usr, I see that from the file path you posted. Say the new system had the login of joe. Then the copy needs to go into that directory c:/users/joe, the end result should be c:/users/joe/JMRI. Same relative path but a different login name.
?
What you don’t want to see is something like c:/users/usr/JMRI/JMRI, that means you got it one directory too deep.
