iTunesMobileDevice.dll is Missing From Your Computer [Solved]

Often, while installing or launching iTunes or performing specific functions, you may get the iTunesMobileDevice.dll error. The message reads, C:\Program Files\Common Files\Apple\Mobile Device Support\iTunesMobileDevice.dll is either not designed to run on Windows or it contains an error.

This usually happens when iTunesMobileDevice.dll is not stored in the correct directory, is corrupted, or access to it is blocked by the antivirus.

Before you proceed to the solutions, restart the PC, install all pending updates for Windows and iTunes, and disable any active third-party antivirus. If you are getting the missing iTunesMobileDevice.dll error in an app under development, make sure to add the directory to the System Path under Environment Variables.

How can I fix the iTunesMobileDevice.dll missing error?

1. Add or replace iTunesMobileDevice.dll in Mobile Device Support

When iTunesMobileDevice.dll is not found, your primary approach should be to add or replace the DLL. As for its storage path, the iTunesMobileDevice.dll location in Windows is: C:\Program Files\Common Files\Apple\Mobile Device Support

Go to another computer running iTunes and the same Windows iteration and architecture > copy the DLL to a USB flash drive > connect the flash drive to the affected PC > move iTunesMobileDevice.dll to the same location > restart the computer and check for improvements.

2. Repair Apple Mobile Device Support

1. Press Windows + R to open Run, type appwiz.cpl in the text field, and hit Enter.
2. Select Apple Mobile Device Support from the list, and click on Repair.
3. Click Yes in the UAC prompt.
4. Wait for the repair to complete, then reboot the PC, and verify whether iTunes launches without throwing a missing DLL error.

3. Repair/reset iTunes

1. Press Windows + I to open Settings, go to Apps from the navigation pane, and click on Installed apps.
2. Search for iTunes, click on the ellipsis next to it, and click on Advanced options.
3. Click on the Repair button and wait for the process to complete.
4. If the missing DLL error persists, click on Reset.
5. Again, click Reset in the confirmation prompt.
6. Once done, launch iTunes and check for improvements.

Since iTunesMobileDevice.dll errors usually appear while running iTunes, you will also need to repair/reset the software installation. Remember, these options would only be available for iTunes downloaded from the Microsoft Store.

4. Whitelist iTunesMobileDevice.dll in your antivirus

1. Press Windows + S to open Search, type Windows Security in the text field, and click on the relevant result.
2. Click on Virus & threat protection.
3. Click on Manage settings under Virus & threat protection settings.
4. Next, click on Add or remove exclusions.
5. Click the Add an exclusion button and select File.
6. Navigate to the path where iTunesMobileDevice.dll is stored, select the DLL, and click Open.
7. Once done, restart the computer and check for improvements.

If Windows Security is deleting or quarantining iTunesMobileDevice.dll every time you add it, whitelist the DLL. As for other third-party antivirus solutions, check their official website for the exact steps to create an exclusion.

5. Reinstall iTunes and other Apple software

When nothing else works, you will have to perform a fresh install of all Apple software and components, including iTunes, Apple Mobile Device Support, Apple Software Update, and Bonjour, amongst others.

If a quick removal doesn’t work, use a top-rated software uninstaller to wipe all traces of the app, including leftover files and Registry entries, before proceeding with the reinstallation!

Also, for some, installing iTunes from Apple’s official website instead of Microsoft Store did the trick. So you may try that as well!
