Eliminate copy of installer

Is there a way to prevent the setup.exe from being copied into the install directory?

Well not before the setup is started, but you can always do:

IfFileExists "$INSTDIR\setup.exe" 0 +3

MessageBox MB_OK|MB_ICONSTOP "setup.exe was found in $INSTDIR.$\r$\nIt will be deleted."

Delete "$INSTDIR\setup.exe"
