This is a undocumented subtlety, but `ENG_ARCHIVE` can actually be a list of paths (like the PATH env var) separated by `:`.  This allows for testing where the MSID files are located in multiple places.  Will it work to skip the `ENG_ARCHIVE` test here  and just do the `remote_access.enabled` test?  Otherwise in the Windows env. you could set `ENG_ARCHIVE` to something special?
