Have you authorized admin session on NAS before starting setup?
Setup by default request elevation and that change all authorization context
of the application. Even mapped drive letters are different for elevated
process.
Can you try to start elevated cmd.exe, make sure you have correct maps/write
access to  destination directory in there and start setup.exe from it?
