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.
