GOT IT FIXED..!!

Battle.net Update Agent (Agent.exe) Issues
Issues with the Agent helper program may prevent Diablo III from installing or updating properly. If you notice your installation hanging at Updating Setup Files, or if you receive errors specific to Agent, try the following steps:

Bypass your router by plugging your computer's ethernet cable directly into your modem
Stop the installation process if it’s still running.
Wait for at least one minute. Ensure that Agent.exe no longer appears in the Processes tab of your Task Manager.
Restart the installation.

If that does not resolve the issue, delete the C:\ProgramData\Battle.net folder and try the installation again. The launcher will automatically rebuild this folder. If you cannot locate this folder, try these steps:

Click Start (Windows Key + Q in Windows 8)
Click Control Panel
If you are in Classic View:

Select Folder Options

Click the View tab

In Advanced Settings under Hidden files and folders, select Show hidden files, folders, and drives.

Click OK.
If you are in Category View:

Select Appearance and Personalization

In the Folder Options section, select Show hidden files and folders. This will bring up the Folder Options window.

Click on the View tab.

In the Advanced Settings section under Hidden files and folders, select Show hidden files, folders, and drives.

Click OK.
Try again to navigate to the proper folder:

Windows Vista/Windows 7/Windows 8: C:\ProgramData\Battle.net

Windows XP: Documents and Settings\All Users\Application Data
Delete the folder, then reattempt the installation.

I am having this issue as well and so is one of my friends, we have looked under the task manager and have not seen the agent.exe, the wow.exe, or any of them running after we close the updater, we let the updater run for about 2 hours and didn't move, but we aren't even getting to the actual launcher update we double click on the wow icon and than it brings up a white window saying launcher updateing and than a bar moves and sits at one spot at I would probably say about 75% and sits there forever....how can we fix this?

I have deleted the battle.net-files to make a rebuild, I have even succesfully reinstalled the entire game, but every time I try to open Diablo 3 it starts updating the blizzard launcher again. If I remove the battle.net-files again, then I am able to play it YES. The game-screen appears after asomewhat hesitant Update of the update agent (go figure). But only for once. Because if I quit the game and then try to reopen, the same problem persists. Quite irritating. Tried a lot of things already. Nothing helps. I thought my computer was giving me this trouble, not the game. But now I see that quite a percentage of people are having the same problems. I would like my credits back for this game, Blizzard-folk. The money spent isn't worth the troubleshooting I have experienced. Not by a loooooong shot...

I can get to updating blizzard launcher but it will eventually fail with: Error: BLZAPPBTS00001. I've tried every single fix in this forum and associated links: Secondary logon, compatibility/administrator fix/program data clear/agent.exe shutdown. I've also tried advanced system care, which although it is a great program and I love it and will continue to use it didn't fix it either. Hopefully the service pack for Windows 8 coming out in a few days will fix it? Or has Blizzard simply decided that my purchase of these products is no longer valid?

Windows 8 is not a supported operating system for D3. So, that might be the issue. This is the official link for that error. https://us.battle.net/support/en/article/BLZBNTBTS00001 See if you missed anything.

The following list might help as well. Try the ones you have not tried yet, especially the part about windows explorer.

-Ensure your firewall or antivirus software is not blocking the launcher. You may have to temporarily disable it.
-Ensure Internet Explorer can access the internet, even if you don't use it as a browser. Be sure it is not set to work in offline mode.
-Ensure you have the latest version of Flash for Other Browsers.
-If you are on a campus or public facility some will block P2P software which is what Blizzard uses. In the launcher tools menu you can disable P2P, although this will slow patching time.
-Ensure Secondary Login service is enabled https://us.battle.net/support/en/article/enabling-windows-secondary-logon-service
-Ensure you are running as Admin https://us.battle.net/support/en/article/run-in-administrator-mode
-Some third party software can interfere with the launcher so you can try running in Safe mode with Networking enabled. Beware your antivirus will be off if you do this.
- Sometimes odd things work such a DNS flush https://us.battle.net/support/en/article/ip-release-renew-and-flush-dns

If those do not work, you can try deleting the Battle.net Tools and Cache folders to clear any corrupt files
