"Can't open" - just downloaded

Hu guys,

I've just downloaded the game and when I try to launch this messages pops out:

Can someone help me?

Solved!

For me this worked:
1. Open a Terminal
2. Open your "Wolrd of Warcraft" with right click and select the "Show Package Content" option.
4. Open the Contents/MacOS folder.
4. Type into your terminal "chmod u+x "(space is important!)
5. Grab and pull your World of Warcraft from MacOS folder.
5. The whole command should looks like after this: "chmod u+x /Users/username/Downloads/World\ Of\ Warcraft\ Wotlk\ mac/World\ of\ Warcraft.app/Contents/MacOS/World\ of\ Warcraft"
6. Press Enter, if you got no error you can run your World of Warcraft without any problem!

As you see this is a different command than before, and for me it worked.

It's not working still. :/
