NexusInDesign 4.2.1

Fixed

• get.ps1 no longer fails with "being used by another process" when a scanner briefly opens the freshly copied
  executable (the failure seen once with NexusAGYmail in NexusSystem's pack job on a fresh Windows runner). The package
  is never run before installation: its version comes from the executable's version resource, the copy staged beside
  NexusInDesign.exe is renamed into place, and only then is --version run from the installed file; if it does not
  answer the expected version, the previous executable is put back. A rename held by such an external, transient scan
  (sharing, lock or access violation) is waited out for at most 10 s; any other error still fails the installation.
