Hello group,
this is my auto update procedure:

start program files\prog.exe
check for updates
loading new prog.exe from a webserver in a download directory
start update.exe (command 'Diagnostics.Process.Start') and close
prog.exe (command 'dispose')
update.exe moves the new prog.exe from \download to \program files
->here is the problem! prog.exe is in use!

any ideas?
