So about that Sims 3 update...
When I said yes I want to update, apparently it was supposed to close The Sims 3 launcher when it did that... it didn't.
Why does it need to close the launcher? Because for some reason, the update for the game application can't install when the launcher app by which you acquired said update is still running.
Oh, but what does it do if it forgot to close the launcher and tries to install? Does it let you simply close the launcher and resume the installer like any other installer in the world? No, it closes itself with a message that you can't have the launcher open. But then the only way to execute the file is by clicking on it in the launcher... and when you try to run it again after this, it simply reminds you there was an error... so apparently it refuses to try again... due to the error of the launcher, the only way you can execute the update installer, being open.
So what happens if you close the launcher? IT FUCKING DELETES THE 1.3GB UPDATE FILE THAT IT DOWNLOADED AT ONLY 470KB PER MOTHERFUCKING SECOND. And then what happens when you push the update button? It closes the launcher like it should have the first time (inconsistent much?!) and starts downloading the update again...
PRAISE GABEN! VIVA LA STEAM!
