You can try this approach:

• go to Launch Conditions Editor in your setup project
• create a new file search and configure it to find your file
• remember the installer property used by this search
• go to File System Editor
• select your file

• in its Properties pane set Condition field to the search property negated; for example, if the search property is named MY_FILE_SEARCH, the condition can be:

  NOT MY_FILE_SEARCH

This way the file is installed only if the search doesn’t find anything.
