The following function may help:

;---cut here---
FUNCTION CHECK_DEMO_MODE

;- Check for demo mode consistently in IDL versions 5.0, 5.1, 5.2
;- Returns TRUE if IDL is running in demo mode.

if float(!version.release) lt 5.1 then begin
  return, demo_mode()
endif else begin
  return, lmgr(/demo)
endelse

END   
;---cut here---

Then all you need in your starup file is

if check_demo_mode() then exit

Cheers,
Liam.
