iTunes 12.3.0.44 does not recognize connected iPad or iPhone

Thank you for the solution. It worked on me.

Tried removing and reinstalling iTunes and related software and still get the "an invalid response was received from the device." message for an ancient iPod Touch after upgrading to iTunes 12.3.0.44 on Windows 7. The iPod connects to a MacBook Air with an older iTunes fine using the same cable and I've tried two USB ports on the PC.

Same issue. Had to uninstall the new and re-install the previous version and it worked right away. Will hold back updating until i am certain the issue has been fixed.

I finally got my iPod to sync again by downgrading to the previous version of iTunes!

First, follow directions at Remove and reinstall iTunes and related software components for Windows Vista, Windows 7, or Windows 8 - Apple Support to remove iTunes and related components and restart the computer.

Then download iTunes 12.2.2.25 from the links at the bottom of http://www.redmondpie.com/download-itunes-12.2.2-for-windows-and-mac-os-x/ (the link for Windows 64-bit is https://secure-appldnld.apple.com/itunes12/031-31877-20150813-B245948E-41B7-11E5 -A7F4-910D11BA098F/iTunes6464Setup.exe). I can't find this link anywhere on apple's website.

When installing iTunes uncheck the box to automatically update so it doesn't try to re-install the broken version.

Everything is back to normal and there don't seem to be any issues from having the music library modified by a newer version of iTunes.

Hello I have this problem as well tried to sync my IPhone 5s this morning after upgrading to Windows 10 Laptop can see my phone but it will not sync. ran I tunes diagnostic test and it recommended reinstalling ITunes which I did but still no sync.

Windows 10 advises you join something called groove which stores all your music on it's cloud then download the app from iTunes.

I tried all of this and it still doesn't work!!!

Apple/Microsoft... come on guys & gals get this sorted please it is frustrating a lot of your customers, i'm due I phone upgrade soon was thinking of a IPhone 6s but now thinking of going with an android phone if I can't get this sorted!!!!

I have the same issue. I just updated to iTune 12.3.0.44 on Windows 10. It is not recognizing my iPhone 6. Frustrated...........

I was struggling with the same problem until an Apple employee finally fixed it! The key is to completely uninstall ALL aspects of Itunes before reinstall. Go through your program list and there is about four different programs that need to be uninstalled including Bonjour ects.

Thank you thank you thank you! So needed new music on my iPod and not able to sync, tried reinstalling and 50 other things. You rock 😎

Thank you so much. I followed your link and it worked.

I was having this problem since the September iTunes and IOS updates and was dealing with it with a work around that I had found here by letting the troubleshooter in Windows Control Panel / Devices for my iPhone recognize my iPhone in Windows Explorer.

AND THEN last week Microsoft pushed the Tuesday Monthly updates out one of which hosed my Outlook. Microsoft reissued the KB in the early morning hours of last Wednesday and my Outlook troubles were fixed. What I did notice was that my Temp directory was filling up with MSI*.Log files and found the Event Viewer wasn't running because the service would not start. I chased this around for most of yesterday then found a fix for the Log files / Event Viewer Problem. Somehow my Windows/system32/LogFiles/WMI/RtBackup subdirectory had lost SYSTEM permissions. Found this out from a web search that restoring the SYSTEM permissions to that sub-directory fixed the LOG files and Event Viewer problem.

This morning I started iTunes and when I plugged in my iPhone it was once again showing in Windows Explorer without having to run the Device troubleshooter. Thought maybe it as a fluke and disconnected my iPhone, shutdown iTunes and powered off the PC.

When I powered the PC back on, started iTunes and plugged the iPhone back in the iPhone was showing again in Windows Explorer.

Not sure why the permissions changes to that sub-directory would have to do with the iPhone not showing in Windows Explorer, but thought I would share what I went through

I have windows 7 and an Ipod that wasn't recognized by Itunes.

After wasting hours uninstalling, reinstalling and rebooting and getting no results, it turns out that the problem was caused by my Ipod device not having been assigned a drive letter. It was an easy fix to do, as per the 2 articles below. It just wasn't an easy fix to find.

Had same problem, wouldn't recognize either my iPhone 5s or an older iPad 2. Went through Apple's troubleshooting steps, no joy. Removed and reinstalled iTunes and it works again.

Thanks billhep1 - this worked http://www.technipages.com/itunes-fix-iphone-or-ipod-not-detected-in-windows

Emanuelco YOU ARE THE MAN!!!!!!!!!!!!!!!!!!! I never post in the Apple forums but this particular issue was driving me insane. I tried all of the other suggested solutions and your solution was the only one that worked for me. I am on Windows 10 on an Lenovo Ideacentre
