You can't do it without reopening but you can get updater message before you start WoT. Look at this: http://forum.worldoftanks.eu/index.php?/topic/499114-aslainupdater/
I get another idea. I add this messagebox that shows when user click on download button:
Can you create new adf.ly link that will reference to some "Thank you" page or something like that?
I mean that actual in game update check is waste of time. You have to exit World of Tanks go to Aslain's website download update and install it. With my updater you can run update chcek on computer boot or before WoT start, you don't need to exit WoT or wait to open browser.
I will try to do that you will get your clicks.
