One thing you should do, once you get TTX opened, is to
1) go up to the menu and select "Online"
2) then from the dropdown menu, select "Updater Preferences".
3) Then select the one where you don't have an internet connection. That "should" stop the prompt to update at every start.
You may be able to install the manual update after that.....without a subsequent prompt to again update.....(but I can't test since I won't bother to buy TTX until after the next major update.)
