When I attempt to upgrade an app in iTunes for windows, I get an error: "Could not purchase. An unknown error occurred (11111). There was an error in the iTunes Store. Please try again later"

Same here... Tapping the update button many times worked for 2 apps for me but don't want to do it for the other 12 apps I still need to update. Hoping for some updates in this thread.

Hello,

I've just received a first reply by Apple support, it's quite good news IMHO:

"XXXX here, from iTunes. I'm sorry to learn you encountered error 11111 when trying to update the various apps from your iTunes Store Account. I can certainly appreciate how eager you are to have this issue addressed and I would be happy to share information with you.

It appears many others have encountered this error and difficulty. Our engineers are currently investigating the issue and working on a resolution. As soon as additional information has been made available, I'll be sure to pass it along.

Many thanks for your support and understanding, YYYY! It's very much appreciated!"

So, as I hoped it's a widespread issue unlike similar issues in the past which were dealt with one by one, case by case. The Store is too critical for Apple to leave such a bug open for a long time. Fingers crossed everyone!

Sam thing I heard yesterday afternoon over the phone.

i've the same problem. please apple help me.

I had same issue in iPhone 4, iOS 6.0.1. Only thing that works for me is keep tapping update. I didn't have time to call apple to get vague tech support answer.

Same problem here, One account on 2 devices (iPhone 4S, iPad). I can download new apps but can't update apps on any device or from itunes.

I have the same arrors with windiws iTune and from IOS devises on my account.

Update: This appears to be a server-side issue on Apple's end. Connecting from an AT&T LTE connection gives the same results as wi-fi. I was eventually able to update a few apps, but it's hit & miss.

I've already rebooted all devices, changed my billing information, signed out of all devices, made sure iTunes is updated, signed in/out with iTunes.

You can (apparently) improve your chances of updating by:

Settings > iTunes > Click AppleID and Sign Out

Make sure the App Store app is NOT running in the background (double-tap home, and click/hold to remove)

Open the App Store, and attempt to update the FIRST app in the queue (sometimes Update All works as well)

It will ask for your password. If it fails the first time, try 5-10 more updates. Then, give up, and start over Signing Out again.

This seems to produce better results then just repeatedly clicking on an Update button repeatedly, but eventually that seems to work as well (20+ clicks?) YMMV, and honestly, this "Sign out" dance above may only *appear* to help things. The main reason this approach might improve results, is that the App Store app may *cache* results, and signing out may force it to start clean. My guess is there's some bad data or code on many of Apple's load-balanced web servers, and just takes a high number of attempts to get lucky and hit a server that's not affected.

My suggestion: If you have the time, continue to call Apple support.

Please report this thread to them: #4518778

I also have this issue- the only resolution I have found is to continually tap the Update button and eventually it will load. when I try from iTunes I get the 11111 error as descirbed above.

I have a 4s running iOS 6.0.1.

Same problem for me.

I havé called Apple this morning, and told them about this thread

I hope this pb Will be solved quickly

have same issure for a few days now but i have some sort of sulotion. on my iphone 5 in the update tab of the app store I kept tappling the install button constantly for each app and after about 30 seconds it downloaded and updated.

SOLUTION

Thanks...that does seem to work, but it isn't really a solution. Especially if you are running iOS 5.x

Glad to finally see that I am not losing my mind and/or the only one having these issues. Not that I would want to wish this on anyone, but I have just spent the past two days trying to figure out what the heck is going on.

Same here - Iphone 4s, Iphone4 and Ipad - can not update Apps and getting 11111 error on ITunes - I have uninstalled and reinstalled and have done everything that I can think of.

Hope it gets resolved - I have 36 apps needing updating on the phone.

Hi guys,

i got this error on my iPad2 and iPhone 4S, too.

Asking Applesupport don´t give me a hint since two days...

I'm having the same problem:

- Can't update/reinstall apps on iPhone 5

- Can't update via iTunes (error 11111)

- Can't update Mac App Store apps.
