$returncode = EXIST ("C:\Documents and Settings\All Users.winnt\Start Menu\Programs\Startup\ifagent.exe")
$returncode = EXIST ("C:\Windows\start menu\programS\startup\ifagent.exe")
If $returncode=0
RUN \\INTS1\INSTALL\IFAGENT\IFAGENT.EXE EXIT
ELSE
EXIT
ENDIF

If the file is present (return code of 1) I still get a message that the ifagent was installed. I only want to execute the install when the file is not present (return code of 0). I get the install regardless of my return code. Why?
