check for newer version

[monte]

hello, in the beginning of my code I look for a newer version (on a network share) and if found copy it to my program's location (c:\program files\). Only it's not copying, is this because it can't over write a running executable? If anyone knows how to replace the current running version of a program with a newer one, please let me know. Thank you.

;make sure there are no updates
if FileGetTime("\\network_file_share\myProgram directory\myProgram.exe", 0, 1) > FileGetTime(@ProgramFilesDir & "\myProgram directory\myProgram.exe", 0, 1) then
  filecopy("\\network_file_share\myProgram directory\myProgram.exe", @ProgramFilesDir & "\myProgram directory\myProgram.exe", 9)
  msgbox(0,"Program", "Newer version found, rerun the program after this window closes.")
  exit
endif

Easy peasy.
