Hidden windows shares

I can find answer with forum searcher.
How I can execute file placed on hidden windows shares, for example

  ExecWait "\\\\softserver\\distr$\\setup.exe" 

I have this message

1 warning:
  unknown variable/constant "\\setup.exe" detected, ignoring (test.nsi:30) 

ExecWait "\softserver\distr$$\setup.exe"
if $ is a part of dir name. Full path might be safer.
