title: Install shield cannot replace locked file
body: <p>I use install shield to update application. </p>
  
  <p>I have ws2003 server, multiple users can access at the same time. </p>
  
  <p>When other users run my application I can run upgrade process, Install shield recognize that files are locked and creates temporary version of new files (these are app.configs, automatically generated during installation) in application directory. It should replace these files after computer restart, however when I run computer again temporary files disappear and new version of files are empty, so my application crash.</p>
  
  <p>It is strange because sometime ago I tried this mechanism in other application but there I replaced simple dll file and it worked.</p>
  
  <p>What can I do to overcome this issue ?</p>
