iTunes keeps crashing when trying to log in - Windows 11

Open iTunes in “safe mode” (without external plug-ins) by:

Control-Shift (while opening iTunes)

and see if it still crashes. If not, that may give you a clue as to what is going on. Then look at the iTunes launch errors caused by iAdCore.dll and Install missing components section in:

Troubleshooting issues with iTunes for Wi… - Apple Community

BTW, are you installing iTunes from the Apple site or Microsoft Store? What version?

I've also tried everything here and nothing works. Just a few days ago iTunes was working fine, but today it would not start. After uninstalling and reinstalling, the app will now start, but it crashes when trying to log in.

BTW, because Apple forced Windows users to the Microsoft Store for current releases, some of the older troubleshooting/fix instructions (check the help menu for updates, running installer as admin, etc.) that applied to the older stand alone versions are irrelevant. All the links provided up to this point, go to the same article with this outdated information. Please take this as constructive criticism. Five links to the same page where most of the info is for old versions of the software doesn't provide users much to work with.

As a potentially useful side note, I've used the Windows uninstaller functions to also reset and repair the app and deleted all the directories pointed out in the links provided (that was potentially useful info). When I start the app now, I'm asked to agree to the license terms, then my entire library is fully accessible, but because I can't login, Apple Music is entirely inaccessible on this PC. This also means I can't authorize my PC, so (although I haven't tried yet), I'm guessing that backups aren't going to work either.

I'd really appreciate a fix for this before. Lacking access to paid services and the ability to back up my phone is problematic.

Yeah something is messed up with the Microsoft installer script or something. I had the same experience trying to install it from the MSFT store. You have to uninstall it and then grab it from the apple website, click "download other versions" rather than the button which will take you to the MSFT store. If you download it and install it directly from Apple it will work.

Thanks for this! I've been searching for solutions for about two months now and this is the first thing that has worked!

It would be really cool if Apple and Microsoft would do what is necessary to make the MS Store version useable, but given how long this has been going on, this doesn't seem to be a high priority.

I kept having a similar issue with iTunes crashing or locking up (new PC Win11Pro), even just attempting to go to the Store or trying to create a new AppleID. One message that kept coming up when launching iTunes was "you don't have enough privileges".

So I right-clicked on iTunes and "ran as administrator". That solved everything! I was able to log into my account, access the store, etc.

I've never had to run iTunes as an administrator on any previous PC (and my Microsoft account is the administrator for the PC) so not sure what was going on. Anyway, all working now!

Make sure you follow all the uninstall steps in the Removing and reinstalling iTunes and other software components section of:

Thank you stumbling upon this solution. I have also been struggling with the same thing.

I had same issue on Win 11 but I installed the Realtek DCO audio driver and the Intel Serial IO driver update for the MoBo, and the issue was resolved, in my case.
