What is error 45054?

I don't know. As far as I know there isn't one. There's an error -45054 but that's 90108 offset from the one you're asking about. (There's been multimillion dollar errors for small omissions and I hope you're not a doctor, car mechanic, or airplane pilot if you're really asking about -45054. 😉)

iTunes error -45054 - https://discussions.apple.com/thread/5469367?answerId=23478840022#23478840022 - permissions error, try repairing disk permissions using Disk Utility.

Using Disk Utility to verify or repair disks - http://support.apple.com/kb/HT1782 - Ignore false warnings this may produce.

If repairing permissions using Disk Utility does not work, try: iTunes: Missing folder or incorrect permissions may prevent authorization - http://support.apple.com/kb/TS1277

Hello from France,

For me reparing permissions doesn't work.

So i download itunes.11.2.2.dmg and only reinstall it .

And it's O.K.

Best regards

PS: sorry for my poor english

Thanks. Repairing the disk helped.

hi friends, I tried repairing the dirk and it did nothing, I still cannot authorize my computer for iTunes which means I cannot match it with my iTunes purchases and all that fun stuff I was looking forward to. I do not want to try the terminal thing because I do not want to mess up, and because the computer is so new it has the latest version of iTunes.. I do not know what to do.. I just got it today too :/

Hello from France,

please, download last itunes, and install it on your Mac.

bests regards

Hi, this worked for me. Go to my computer, click local disk, then double click program files and open the itunes folder and find the itunes folder icon. Right click "run as administrator" then pin it to your task bar or wherever. I'm runnin windows 10 64 bit and it solved the issue 🙂

I´m runnig w10 64bt too but every time that i try to play any song in apple music, show this error -45054 (???!!!)

and also my iCloud songs dissapeared.(??!!)
