I recently registered all my older serials for Warcraft III ROC, TFT and the original Starcraft games on battle.net, and decided to download the Warcraft games onto my MacBook Pro. I went to the download page for ROC and the download of the zip file functioned just fine, and it extracted just fine as well, giving me an icon called "Downloader." However, upon double-clicking this icon, nothing happens. I downloaded it multiple times and got the same result. Frustrated, I moved on to TFT and Starcraft, and again the Downloader fails to launch every time.

I next tested the ROC downloader on a separate machine running 10.5.8 to see if it was just me, and it worked like a charm. Clearly there is some kind of issue with either OSX 10.6.5 or with the Downloader itself, but some googling and forum searches turned up no leads. Did I somehow miss something obvious?

Any help would be appreciated, thanks.

What are you using to unzip the file? If you're not using the built-in OSX Archiver, try using that instead.
