fresh windows "the application was unable to start correctly (0xc0000142)"

Try the following in turn until iTunes opens/reopens normally:

• Remove any SD card that might be in a card reader.
• Exit the BTTray.exe Bluetooth utility if installed.
• Locate the shortcut for iTunes, right-click on it, and select Run as administrator. Doing this once may fix certain launch issues. Some users were finding that with the 12.6.1.25 build they had to use this method every time and modified the shortcut accordingly.
• Try holding ctrl+shift as you launch iTunes so it opens in safe-mode. Again doing this once may sometimes help.
• Delete the iTunes shortcuts from the start menu, desktop, task bar, or similar, then repair iTunes from the programs and features control panel.
• Try Fix unexpected quits or launch issues in iTunes for Windows - Apple Support and test the behaviour in a different user profile or with a different library. If the problem only exists in your profile it may be possible delete some of the iTunes preference files which it would seem that iTunes may be choking on. We can go into details later if the issue is limited to your own profile.
• Temporarily disable any non-Microsoft anti-virus and see if that has any impact on the behaviour.
• See the second box in Troubleshooting issues with iTunes for Windows updates for detailed tear down and rebuild advice. Disable any non-Microsoft anti-virus software when reinstalling and run the installer as the administrator. In some cases users have had to completely remove some AV packages to get iTunes installed properly.
• Or see the iTunes installers section of the troubleshooting tip and reinstall the last version that worked correctly for you.

Looking back at the original post try removing any compatibility options from the iTunes shortcut.

Since this thread started iTunes 12.6.3.6 has been released, which should support iOS 11 and newer devices in a version that retains the app management features that were removed in 12.7.0.166. You might find that version is better behaved for you.

iTunes 12.6.2.20 for Windows (64-bit) worked. I did not try to upgrade after.

Well I don't think Windows Defender will be a problem, and the reports seem to indicate that the right versions of the support files are installed. Is the behaviour any different in a new user profile? Can you roll back to iTunes 12.6.2.20?

Can you roll back to iTunes 12.6.2.20? - Yes 12.6.2.20 works without issues.

Next problem: When I sign into iCloud on my desktop I get the error "iCloud has stopped working".

When you reinstalled iTunes did you right-click on the iTunes installer and use Run as administrator?

What anti-virus package do you use?

Thank you, CR3STOM!

Issue is fixed by timezone change.

The problem is in the system settings of time zone, it can be solved by replacing your time zone to another, which has the same difference from UTC +00:00. Example: change UTC +07:00 Barnaul, Gorno-Altaysk to UTC +07:00 Novosibirsk.

Reinstall iCloud for Windows - Apple Support? 😕

tt2

Fair enough. You'll probably need to update if you upgrade any iOS devices to iOS 11.

tt2

I think 12.6.2.20 works with iOS 11, but probably nothing earlier.

After update to latest 12.7 (for iOS 11)...

Same issue: "The application was unable to start correctly (0xc0000142)".

Same Faulting application name: "AppleMobileDeviceService.exe, version: 17.423.0.23, time stamp: 0x54dd6d21"

Same Faulting module name: "CoreFoundation.dll, version: 1.750.35.0, time stamp: 0x596cab27"

Windows Services: "Windows could not start the Apple Mobile Device Service service on Local Computer."

Reinstalling the iTunes according to https://discussions.apple.com/docs/DOC-6562 - unsuccessfully 😠

There must be something with the new release or windows release. I am having the exact same issue. Completely fresh install.

The third suggestion worked for me. Thank you!
