Hello folks,

It appears that quite a few people are having this error.

The solution I have seen so far that appears to work for most people is to simply exit the launcher and open it again (and again if necessary). It may take a number of tries, but it appears to work eventually.

I do not currently have access to a system experiencing this to dink around and find another solution, but I am on the lookout for any other potential fixes.

Some other solutions I have seen that work in certain cases, but not all:

Applying the patch in Safemode with Networking: http://us.blizzard.com/support/article.xml?articleId=21148

Configuring Internet Options
Go to the Control Panel and open up Internet Options.
Click on the Connections tab.
Click the button called "LAN Settings"
Uncheck all of the options on that screen.
Then try again.

If that does not work, go back in and check the box to "Automatically Detect Settings" and test once more.

NOTE: Please make sure that you have the most current version of Internet Explorer, even if you do not normally use it to browse the web. Also, double-check that it is not set to run in offline mode.

Permissions fixes:
Make sure that you are on the administrative account for the computer, and if you are on Windows Vista or Windows 7 try right-clicking on the shortcut and running as administrator instead of double-clicking.

If that does not work, you can also try to take ownership of the entire World of Warcraft folder, which can sometimes fix this.

How to take ownership in Vista/7: http://www.howtogeek.com/howto/windows-vista/add-take-ownership-to-explorer-right-click-menu-in-vista/

How to take ownership in XP: http://support.microsoft.com/kb/308421
If you are still having issues, check to make sure that your antivirus is not detecting a false-positive in the program and blocking the patch. If it is, you will need to flag the file as safe.

Security Software
I have also seen people have success by disabling their antivirus temporarily.

University Network/Public connection
Many public connections will block the patch from downloading. You can contact the network administrator to configure the network to allow the patches, or you can download the necessary files from an external site.

My Realmlist was set for Europe and therefore couldnt download the patch until the europe servers would normally get it. Check your realmlists to see if my problem was also yours.

World of warcraft > Data > EnGB or EnUS > Realmlist.wtf

it should be

set realmlist us.logon.worldofwarcraft.com
set patchlist enUS.patch.battle.net:1119/patch
set realmlistbn ""
set portal us

Try closing the updater and re-opening it from the updater file in your World of Warcraft folder (wow-4.0.0.1807-to-4.0.0.2072-enUS-tools-downloader). I was having the same problem, and this immediately fixed it for me.

Q u o t e:
On Vista:
1.) open your browser and go to tools. ( Internet Exp. over to the right by the blue ? )
2.) go to internet options
3.) go to advanced
4.) you will see different sections (such as Accessibility, Browsing, etc) find Security
5.) under Security, next to the first few check boxes you should see
"Allow active content to run in files on my Computer*"
6.) If that box is not checked off select it to check mark it.

If you're like me and have McAfee and got this error that the launcher cannot receive the patch information then try this:

-Open up McAfee and go to the firewall settings
-Open up the tab that shows a big list of of Program Permissions
-Everywhere you see a "WoW.exe" WoW launcher" "blizzard downloader/uploader" change from outgoing to full (i had this set before but this patch made McAfee ask for permission so I went to checked it again)
-Exit and restart your computer
-Open wow launcher and it should work

Q u o t e:
OK. so i figured it out i think for all you MAC users! All you have to do is refresh and get a new DHCP. Im not really sure what that means but it worked. this is how you do it!

Click the apple (top left)
Click System Preference
Click Networking
Then click on either airport of ethernet. (ethernet if your hard wired on a desktop and Airport if your using wifi)
The click the advanced button at the bottom right.
Click the TCP/IP tab.
Then click renew DHCP lease

Hello Draenn,

Did you try any of the other steps? What were the results? Did they give you any different messages?

---

Q u o t e:
Will there be any work-arounds for college students and other people who have no administrative control over their internet's P2P access? Their issue is similar to this one's, only it's constant with every patch :(

There have been a few floating around the forums for a while (downloading someone else's WoW.tfil file seemed to work), but I'm hoping for something official that doesn't make me worry about downloading a virus or something!

If we're left to lurk on the forums on patch days, so be it. I'd just like to know one way or the other :)

---

Unfortunately, I have not heard of any work-arounds for college students with the exception of downloading the tfil files from other sources.

The best way to handle it is to contact your network admin at the university and ask them to configure their network to allow the patches. Most seem willing to do so, from what I've seen in the past.

That will minimize the chance of viruses and should also minimize the issues you have with updates.

---

Q u o t e:
Hello , i tryed everything , message is the same ( Launcher cannot obtain patching information , please check your internet configuration )

---

What sort of connection are you on, Draenn? Is it wireless or satellite, or a public/university connection?

Go ahead and check to see if your ports for WoW are open.

The easiest way to check is to go to http://portforward.com/help/portcheck.htm and download the free port check tool there.

Then you can follow their simple directions on how to check the ports.

World of Warcraft uses TCP port numbers 1119, 3724, 6112, 6113, 6114, 1119, 1120, 80 and 4000 to play and UDP port 3724 for in game Voice chat. Also please note the Blizzard Downloader, which downloads patches, also uses TCP 3724.

---

Q u o t e:
Still hasn't work for me.

I noticed that the big patch for Cata is still dl in the background, maybe is creating a problem trying to do both patches at the same time ?

---

Hello Yiggles,

Go ahead and try ending all processes for WoW from the task manager and see if the patch will start up after those are closed.

---

Q u o t e:
I downloaded port checker , checked ports and they are closed ( everyone ) -your port is not open or not reachable
Hmm everything was ok until patch comes , btw im using wireless conection , public

---

In that case, you will need to get the ports opened in order to download the patch. Since it is a public connection you will need to speak to the network administrator and request that they set it up for you.

Unfortunately, if the ports are closed you will be unable to download and apply the patch through the normal methods until they are opened.

---

Q u o t e:
I am to having issues with downloading the patch. The error I am getting is Lost Connection to Updater. I have tried downloading the WoW.tfil file to see if that fixes it but it has not. I also did the solutions that was given at the star of this thread same error comes up. I also did a wow repair and still same issue. Anyone know what the issue could be?

---

Make sure that you are on the administrative account for the computer, and if you are on Windows Vista or Windows 7 try right-clicking on the shortcut and running as administrator instead of double-clicking.

If the issue still persists, it is potentially caused by security software.

There are a number of security programs that are causing this right now, so you may try temporarily disabling or uninstalling your security software long enough to get the update.

Otherwise, you may try patching in safemode with networking (http://us.blizzard.com/support/article.xml?articleId=21148) or temporarily uninstalling your security software for the duration of the patch installation.

---

Q u o t e:
I sincerely doubt that it's to "keep people busy." It's probably one of those checklist things that you normally face with tech support ("Did you try rebooting?"). They probably identify the problem as "Oh, that sounds like X problem, here, try this solution it's the one that's causing the problems most often" and then they go from there.

---

That is exactly it. =)

The potential solutions we are listing are things that we have seen fix it for some people (although unfortunately, nothing appears to fix it for all).

We merely have to go down the list until we find one that works for each person.

If none of them work for someone then we will continue branching out from there, but we start with what is most likely to work.

Hello Lorken,

Check that your ports are open. It is possible that there's another firewall on the network or system that is still trying to block the patch.

Q u o t e:
(I have used PFChecker and each of the ports listed said were open but router was unable to be pinged could the issue be the router?)

---

It is possible. What happens if you bypass the router and connect directly to the modem?

---

Q u o t e:
i've done every single thing you've suggested and nothing has changed, i changed the lan settings back and forth after dowloading IE 8, i disabled and uninstalled symantec, i'm on an administrator account, i downloaded the port checker, opened every port you listed, and still not even a hint of any progress.

---

Dayinthelife, when you uninstalled Symantec, did you run the Norton Removal Tool?

Symantec/Norton will leave files behind and continue to block access if it is just uninstalled using the Windows uninstaller.

Try the removal tool at http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20080710133834EN&ln=en_US

Hello Cove,

Did you try downloading the tfil file and applying the patch from that? That appears to be the work-around for a lot of other folks, particularly those on university of public connections.

What sort of connection are you on?

---

Q u o t e:
I've downloaded the TFIL file manually but the launcher wont install it. the launcher still says that world of warcraft is up to date but when i go to play it tells me to download the patch

---

Renay, where did you extract the tfil file to? It should be extracted directly under your World of Warcraft folder.

Hello Jamjar,

---

Q u o t e:

In Safe Mod of Windows, the graphic not high enough to run game,

So...How can i get the new Patch ? ( in Safe Mod )

---

It should only give you that message if you are hitting "Play" on the launcher. Try sitting at the Launcher without hitting "Play" and see if the patch will apply.

---

Q u o t e:
Its something with the Blizzard download servers I just installed the game on my desktop it also gets the error and so does a friend of mine. the error happens at either 0% of applying the updates or after applying the updates like right after the Setup section of the patching.

---

I will not completely discount it, however I have tried patching on 3 systems (even outside of the Blizzard network) and have not been able to duplicate this. Also, the fact that we have found solutions for a large number of people tends to lead me to the belief that something on your network or system is being finicky.

What sort of network are you on? Is it a public or university connection? Those appear to be the most common factor in these errors, from what I can see.

---

I have seen this error caused by two base issues:

1) another launcher is already running in the background.

-Hit Ctrl+alt+del and go to Task Manager
-end any processes associated to WoW such as Launcher.exe.
-try the patch again

2) You are unable to download the mfil file due to something like a proxy, a public connection, or a security program.

-Go to the Control Panel and open up Internet Options.
Click on the Connections tab.
Click the button called "LAN Settings"
Uncheck all of the options on that screen.
Then try again.

If that does not work, go back in and check the box to "Automatically Detect Settings" and test once more.

-If you are on a public connection, contact your network administrator to allow the appropriate ports for WoW

-Try temporarily disabling your security software to see if it allows the patch.
-Some security programs will require that you fully uninstall them, as "disabling" does not stop the from functioning.

Hello Karkos,

What happens when you try to download and apply the tfil file?

What operating system are you on and what security software do you have installed?

Does your Internet Explorer allow you to load webpages?

---

Q u o t e:
This is a little off basis, but has any of the Dev groups took a look at Power Word: Shield extra GCD bug?

---

I would have no idea. You can check for additional information on the Bug forums.

Kaspersky is typically good about not blocking processes when it is disabled, so that is not likely to be it, although you can certainly try uninstalling it temporarily to test.

Have you tried creating a new administrative user account to see if it allows you to patch from there?

Hello Karkos,

Are you able to go to forums.worldofwarcraft.com if you use Internet Explorer?

Hello Theoldelf,

If your son's system was able to download it with no issue, the easiest fix would be for you to copy the entire game folder to your own system and replace the files on it with the patched version.

Otherwise, it would still be a matter of narrowing down which settings or security software are blocking the patch download.

Hello Karkos,

What is the error you receive when trying to run WoW.exe directly?

I am running out of ideas on what you can try, but here are a couple of additional ideas I will throw out before I leave for the night (I will be back to check on this thread in the morning).

Try power-cycling your network - http://us.blizzard.com/support/article.xml?locale=en_US&articleId=21227

Copy your World of Warcraft folder to a different location, such as C:\, and then try running it from there.

Make sure that your operating system has all of the current updates and is at the most current service pack.

Much less convenient, but potentially helpful if possible: Try connecting on a different connection, or if you have access to someone else's fully patched game you can merely copy that over and replace your existing files.
