Why is the installer on your website only 3.3.7 it wont update to 3.3.9 even with the offline installer 
Impossible it won't update with the Offline installer provided, of course:
- You download again the Offline installer. Since it's offline, it can't update itself so, you must download it again every time there's the smallest update.
- You installed the Offline installer *after* the normal Live Update.
