Cant start an Installer ( Wow BC Installer )

[Bettarg]

Hello,

after countless time , i have managed to install OSX and bring up working everthing....

The i download the newest WOW BC installer from WOW-europe.com.

When i doubleclick it... nothing happens. The Icon flash´s , and it do nothing.

I have Patch my Rosseta , but i dont think this is the problem , becouse the Installer should be a Intel Nativ application.

My System :

Amd Opteron 170
IDeneb V1.3 10.5.5

Can someone pls help me ?

Thanks a lot and sorry for my bad english
