Starcraft 2 - Installation Help

I have just bought Starcraft 2. I am in the process of installing it and it installs successfully, but then has to do some updates!

It has been updating for about 20 minutes and when it gets to 100% it starts again!

I have counted; 7 times has it has done the same update. what is going on?

Solution 1:

Starcraft 2 has been out for several months now, and while the game itself has been updated (aka "Patched"), it is cost prohibitive to apply the same patches to the assembly-line copy that new DVDs of the game.

Just keep at it, and you should eventually reach the end.

Alternatively, register your game with battle.net, and you can download the latest version of the game directly from Blizzard themselves. This may not be an acceptable alternative if your internet connection is particularly slow.
