iTunes version 12.12.0.6 only works on English-language Windows, crashes on startup when Windows UI is in a different language

I can't consolidate my files because my iTunes doesn't open anymore. But I will try follow the steps froms "Restore your library from a backup". I think with this method, I don't need to consolidate the files.

Thanks!

I have the same issue and my Language is set to English United Kingdom. If I switch to English US, log out and in again then ITunes does a reinstall and works. Change the Language back to English UK, repeat the process and ITunes stops working again

Install U.S. language and set to default. You'll have to put up with some weird/ annoying keyboard oddities until the bug is fixed but I can't imagine it will take longer than a few days, then set your native language back to default at that time.

I have tried all the steps given. I changed the language from English UK to USA. This did not work. I removed I tunes and downloaded an older version. This did not work either. What do I do to get this working again. This isn't very good customer service!

I’ve been having a nightmare with this all day, thinking I’d done something by accident! I’m so glad I ended up googling it and realised it’s an iTunes issue worldwide. I’m in the UK, I’ve just reset the language to English US, downloaded the language pack and I’m back in action. I hope they fix it soon, what a ridiculous bug!

Not really a surprise anymore, but the Dutch version has the same issue. I actually tried some other languages as well and can conclude all versions exept the US-Englisch one are affected. However Apple did stop the enrollment of 12.12 trough "Apple software updates", the latest version there is now 12.11.4. In iTunes itself however the update to 12.12 is still visual an d will (as now known) cause the problem when executed.

Good that they stopped enrollment but it’s too little too late. Many many thousands already taken the plunge. They need to push a new update pronto via Apple software update and in ms store. I am not comfortable uninstalling iTunes and putting an older version up in case it has nasty side effects on my carefully built up library of music. The language change might be an idea but I am worried about unforeseen side effects in my system on other stuff if that is done. I am trying to patiently wait for a new version to be pushed but it is very frustrating. I just hope when and if an update arrives no damage is already done. I already went into control panel and selected repair. Then downloaded via browser the version again and installed, was given option to repair and went for that again. This was all before the bug causing it became clear or else I’d of held off. Same end result anyway. Just hope the library isn’t hosed up.

I have tested this and the error occurs on a Windows 10 64-bit PC in English-UK but NOT in English-US. if you change the Windows Language to English-US without doing any re-installs, repairs or de-installls then the issue goes away following a Signout and Signon to the PC!

Actually, I use iTunes downloaded by Apple’s website. After the update, I can’t use it anymore, then I downloaded from Microsoft Store too and not work as well. So now, I have both iTunes (from MS Store and Apple's website) and no one of them are working.

Looks like a new version may be with all of us soon. I don’t use the store version and avoid Microsoft’s store like the plague. So waiting for the traditional delivery method of ‘Apple software update’ to offer a new version. So far nothing showing up as says I am up to date. I even went to the website for iTunes to download the windows 64 bit version via my browser. But the installer fails saying a newer version exists on my pc. So I am assuming that version is still not updated to 12.12.1.1 bit frustrating, hope this version will get pushed soon via apple software update and my library setup isn’t affected by all this (that’s why I haven’t uninstalled iTunes and put an earlier version on as don’t want to take any risks with my matched library)

I've also spoken to two helpful, but puzzled Apple support personnel this morning. It seems the word hasn't gotten fully around Apple yet as neither were familiar with this issue. After discussion with Apple, I've decided to leave my English-UK PC and the iTunes installation files alone until there's a definitive acknowledgement from Apple about a fix.

Incidentally, the iTunes application is now shown as "not available" in the Microsoft Store, so something is progressing. Meantime, I'm using the Windows "Groove Music" application (such a dire name...)

Thank you for your reply.

With the exception of the keyboard, set to U.S. language, all other language settings are in

English (Canada). System information reports "locale" is the U.S. Do any of the language settings need to be updated to prevent the iTunes error? Please advise.

Thank you.

This morning (23rd September) Apple pushed a new version of iTunes for Windows via the Microsoft store that appears to fix the problem. Suggest you try upgrading to version 12121.1.54014.0. It worked for me, good luck! :-)

Microsoft store reports iTunes "is currently not available." Does this mean iTunes is not available for all Windows users or only users who don't have the required language? No Apple update - we are told files are missing and to reinstall iTunes. Of course if we could reinstall we wouldn't have the problem!

So I've also just been offered the 12.12.1 release through Apple Software Update, this has resolved the 'files missing' error.

If you are still struggling and do not want to/can't change your language setting (to en-US) or are not seeing 12.12.1, please see the link to the prior versions of iTunes in my earlier post.
