itunes 11.4 crashes when syncing apps to ipad / iphone

Check that, took a closer look and saw that the new app was on my iPhone but Ookla Speedtest was "waiting". Removed Speedtest from Library and iPhone and now all looks good. Can add a new app to my Library and can have it added to my iPhone during a successful sync. I thought I had weeded out all the "broken" apps but I see that I hadn't. So jbandes, my experience is the same as yours.

Or maybe what's going on is the NAS housed Library can't "update" apps on the device.

I ran into the same problem about 2 weeks ago. Had iTunes 11.3 on my Windows 8 PC w/ iPhone 5. After upgrading to iTunes 11.4, iTunes crashed when it got to the "syncing apps" part of the sync process. I got no other errors.

I spend HOURS on the phone w/ Apple tech support. Useless. The solution was to down-rev to iTunes 11.3 - then everything worked just fine again. unfortunately, Apple won't supply ANY older [than the current] version of iTunes, so you have to "google" it.

I did another [stupid?] thing today which I'm regretting: I bought the iPhone 6. As luck would have it, the iPhone 6 will not work with anything earlier than iTunes 11.4. I'm running into the exact same problems. CRAP!!! I hope this gets fixed with iTunes 11.5....and soon!!!

I have Win 8.1, iTunes 11.4, IPhone 6 on iOS8.0.2 and have a Netgear ReadyNAS where all my library is stored and have had the same problem as everyone else until 5 minutes ago (IE: Restored my 5 backup successfully to my new 6 but at the sync phase to put the apps back on iTunes continually crashed at that exact point every time). Someone told me to re-download all my apps over wifi back to the new phone, this didn't work - sort of. I say sort of because I noticed a few screwy things. We have had iPhones since the 3G, so we still have some old apps that no longer exist on iTunes, I deleted them from my iTunes Library and iPhone. I also noticed some apps in my Library needed to be located again (They were easily identified as grey icons in iTunes/Apps rather than normal colourful thumbnails in iTunes/Apps), this was a VERY manual process of clicking each one, "Show in Windows Explorer", choose LOCATE and double click on the app's name in the Explore box that pops up (Not all app titles have the same file name either so some detective work was involved - you can right click on it and "Show in iTunes Store" and it may reveal a slightly different name or show it no longer exists). Once all apps in my iTunes library were "colourful" I synced again, it crashed again, but it had copied some more 'greyed' out apps back to the phone (probably ones I deleted from the iPhone 5 but were still in my Library), I re-downloaded on the phone and kept repeating this process until I had no grey apps on iTunes or my phone and all non-existent apps in the app store were deleted on the PC and on the phone and FINALLY it worked. Crap I know, but works at least! There is no doubt a bug in iTunes 11.4 in dealing with iPhone 6 as my iPhone 5 didn't care about all of the above and Apple still needs to fix it.

Side Notes to all of the above: iTunes also automatically syncs my iPh 6 every time I plug it in even though I have auto-sync check box disabled. Plus after the successful sync I only mean successful in the fact iTunes didn't crash but after copying the apps across but the sync wheel was going around on the phone but nothing was happening up top in the grey status rectangle on iTunes (IE: it doesn't go on to do anything else), so I ejected it (got the warning it is still allegedly syncing), put it back in, synced again and it finally did a proper sync and finished correctly.

That is helpful. Thanks!

It's VERY interesting that you didn't have this problem with your iPhone 5 - I did.

I'm going to go waste another hour or five right now.

Confirmed, iTunes crashes during sync when the Library attempts to update apps on the device. As long as I avoid this scenario, sync will occur without an issue.

That's it. I'm DONE! Nothing works. I've tried every manner of deleting, installing, uninstalling, updating, syncing - nothing works. Plus, I just realized that NOTHING is getting synced even though it appears that only at the end of the sync process, when it's syncing the apps, does iTunes 11.4 crash. None of my music, podcasts or contacts get synced. Absolute crap!!!!

Hi,

Do we know if Apple will be providing an update soon? None of my Apps sync through iTunes or Wifi. Pretty poor 😟

Apple you have to fix this. This is unacceptable. Get an update out that will allow users with their library on a homeserver / NAS to sync apps to their Iphone 6 without crashing. This is an embarrassment and will continue to discourage anyone and everyone I know not to purchase and Iphone 6 or upgrade to iOS 8 until you fix it.

Hi,

Experienced the same issue - whenever a device would sync, iTunes 11.4.0.18 would crash shortly thereafter. (W7Pro64). iTunes library is on a NAS which seems to be a consistent theme.

I checked "Prevent devices from syncing automatically" in Edit | Preferences | Devices and it seems to be stable.

Edited to add - we have no IOS8 devices yet - we'll keep them IOS7 until IOS8 + iTunes appear stable.

Hi,

same issue here (BEX MSVCR100.dll).

I tried to sync my iPhone with iTunes 11.4 without any connection to the internet. This seems to work.

It looks like this issue is from Apple Mobile Device Support, and not iTunes. At first, I removed iTunes 11.4 and went back to 11.3.0.54, but it still crashed. Because Apple Mobile Device Support 8.0.0.23 wasn't uninstalled with iTunes. Once I removed that, and reinstalled iTunes 11.3.0.54, with Apple Mobile Device Support 7.1.2.6, it worked perfectly.

So I tried updating to 11.4, removing Apple Mobile Device Support 8.0.0.23, installing Apple Mobile Device Support 7.1.2.6 (extracted from iTunes 11.3.0.54 installer) and now iTunes 11.4 works fine syncing files over the network.

My iPhone is still on IOS 7, and looking at the version numbers of Apple Mobile Device Support, this probably won't work for IOS 8 devices.

It's very disappointing that Apple has let this problem go almost a month without a fix, especially when you see how many views this thread has.

Agreed, I can't believe this problem hasn't been fixed yet.

I had this same problem. However, I noticed iTunes was using the UNC name to reach the iTunes Lbrary on the NAS. I then closed and restarted iTunes holding down the Shift Key (which allows you to select a new library location), and then selected the iTunes library using a mapped drive letter and that appears to have resolved my issue.

By the way, the workaround I was using prior to this, which someone else may have mentioned, was to make sure the apps were up-to-date on both iTunes and the iDevice. Any new apps would also need to be on both as well. You can tell if they are out of sync, because the apps on the iDevice (in IOS8 anyway) will appear grayed/blacked out. While this solution isn't ideal, at least you can still sync your photos, music, calendar and email without any errors.

I am running iTunes 11.4.0.18 on Windows 8.1 with an iPhone 4s on IOS 8.0.2 and an iPad 3 on IOS 7.1.2.

"I then closed and restarted iTunes holding down the Shift Key (which allows you to select a new library location), and then selected the iTunes library using a mapped drive letter and that appears to have resolved my issue."

James, this looks like it may be the best/easiest/cleanest workaround yet. I've seen other suggestions to use drive letter mappings rather than UNC, but if it works for others, your suggestion to Shift-start iTunes and then browse to library via drive-letter looks likes the easiest way for all those apps to get "remapped" to new location looks to be the easiest. It would also probably continue to work as new apps are added, since they will go to the mapped drive letter rather than UNC path.

I'm traveling right now so I can't try it until Friday or Saturday, but I know my library is indeed mapped to UNC rather than drive letter.

My previous workaround, which has worked, was to "delete" all apps from my library, copy the files to local drive, then "re-add" them. This is kind of a PITA because every time I sync one of our 2 iPhone 6's, I end up with new apps going to the UNC path and have to delete them, then re-add at local drive.

It also meant that I had to turn off the setting to have iTunes copy new additions to the iTunes directory & I hate having that setting off.

Now, I wish Apple would just get the *(Y+&**&^ thing fixed before I get home, but if not, I'll try this workaround, which would be cleaner to maintain, and could potentially even be left as is after iTunes does get fixed.

Cheers,

Ray

It worked on me for two PCs, so hopefully it will work for you. It's a simple solution if it turns out it works across the community.
