I googled around a bit for solutions but so far I've found nothing where an actual answer is posted.

I finally got the game to download by using safe mode. ive been able to play since i got the game but it gave me an update warning first then it just wont even let me in at all. What happens when you attempt to open the launcher and accept the update? Have you tried some of the suggestions here such as rebooting your Mac, power cycling your network devices, or bypassing your router and directly connect to the modem with an Ethernet cable? In the Info box, go to the Sharing & Permissions section and click on the lock and unlock it, entering your admin password when prompted.4. Click on the Burst icon (cog wheel) and select Apply to enclosed items If you're on a PC and have this issue, please post in the PC forums, as this is a Mac forum. So, it seems the main culprit of this is the 802.1X option in Advance menu of network settings.

Please check this link for more information: the Beta, several startup issues were resolved by setting the Diablo III tools to run in Compatibility Mode.

At this time, Compatibility Mode for the retail tools is no longer needed.

I start the launcher and it doesn't show anything but the phrase "Updating Tools (0%)" at the bottom with no progress even after having it open all night and the Play button grayed out...

Also when I tried to install Diablo 3 (real version) from I have it downloaded and installing it gets to a certain point halfway throughout the bar and stops with no further progress even after having it open an entire night as well...

or any idea how to fix it (i belive this patch have the patch number 17) Try with peer to peer disabled.

Make sure multiple instances of aren't running (remove all the processes, try again).installers start running today (even though you can install the game, you can't play until midnight PST), a host of issues have cropped up.Most of these can be solved by commonsense troubleshooting techniques, but some others are a bit more .ATI Radeon HD 4600, 4700, 4800, 5000, 60 series products are unaffected, as is Windows XP.Update: ATI has released a Catalyst 12.4a driver hotfix for the affected cards.If your launcher aint opening when you try to install the beta I made a lil guide for you guys how to solve the problem.
