iTunes error code -100000

Maybe try to submit the problem to Apple's Express Lane online:

I had the same problem and have submitted it online but haven't recieved a response yet.

This has been happening to (usually) one or two tracks in each album I've purchased/downloaded in the past month. The song will appear to be downloading just fine, but then, instead of moving on to the "processing file" step, the blue bar will reset and begin filling up again. This will repeat three or four times, and then it will give me the "corrupted file / err = -100000" message. The first time it happened was with a Miike Snow album, and I had to wait about a week and a half (trying to re-download every day) before it would let me download the song. I thought it may only be happening with albums, but now it is happening to random individual songs I purchase as well. Sigh.

its an easy fix. simply go to the itunes store, click your account name in the top right, sign in, and it should download successfully. it downloaded as soon as i put my password in, if it doesnt try checking for available downloads. this method just worked for me and a "corrupted" tiesto track off his new album.

No this does not work. The file still hangs after attempting to download several times. It fails in iMac, iPad and iPod.

It has been about two weeks since the first failure. Other apps and songs work fine. The failing file is track four on Bonnie Raitt Slipstream. the fix you describe is what the tech suggested. It does not work for me.

The same this is happening to me. I think iTunes has some sort of virus that they haven't found yet . Or their site has some serious issues. If this is going to happen every time when I have paid for a download maybe I will discontinue using iTunes. I don't like getting ripped off!!!.

I too have this problem. I just signed up for iTunes Match, matched up all my music, deleted a bunch of tracks, selected to download them back from the cloud, and about 1 in 800 tracks on average has got this error. Retrying works sometimes, but not others. I think there is a checksum in the file and it is failing to match that checksum after downloading. Either the checksum is stored in the iTunes library and corrupt, or one of the iTunes servers has some corrupted copies of the files.

Clearly there has to be some sort of software fix here that will tell the system to re-download a checksum from two sources for the song and store it if they match. Then, try to download the song again, if checksum does not match, try from a different server.

This is most likely a bug in the iTunes code in terms of error recovery.

Before you download the Song I would recommend that you first remove the iTunes Downloads folder to restart the download on your iMac.

You can locate your iTunes Downloads folder in:

Mac OS X:

~/Music/iTunes/iTunes Media/Downloads Note: "iTunes Media" may appear as "iTunes Music. Also, the tilde (~) refers to your Home directory.

After locating your iTunes Downloads folder:

1. Quit iTunes.

2. Delete the Downloads folder on your computer.

3. Open iTunes.

4. Choose Store > Check for Available Downloads.

5. Enter your account name and password.

Hope this works!!! 🙂

I was having similar corrupt file issues when trying to download songs that I had both "matched" and "uploaded" to iTunes Match.

I tried to see if there was a common variable, but I haven't been able to find one.

For example, a few uploaded songes and a few matched songs wouldn't download this afternoon, but a few hours later, they download.

It doesn't seem to make a difference if the upload is stored with applesgussat000002.blob.core.windows.net (70.37.127.110), any one of the s3-external-1.amazonaws.com servers (several ips), or if it comes straight from an apple.com domain-related server.

An interesting tidbit: The first two domains seem to be where the uploaded files go to and come from, while I've only seen matched and purchased songs come from *.apple.com servers. Someone with more network-admin skills might have a simple explanation for this, but I found it interesting.

If this means that Apple is using Amazon servers to host files, yet the corrupt file issue persists across hostings, does that mean there's an issue with either how the Match process creates these checksums, or with the local Mac's iTunes installation's handling of these checksums? In the end, I just want it to work, but I'm interested to know what exactly caused the issue.

I was experiencing this same issue last evening after downloading a seven-song album and one track repeatedly being reported as "corrupted." I attempted to log into and out of iTunes several times and click "Check for Available Downloads" to kick it into downloading ... to no avail.

This morning, I received a troubleshooting email from Apple Support. After attempting the many possible solutions they advised me, the one that worked was temporarily disabling the anti-web-tracking add-on I'd installed on my Firefox browser.

This worked after the following did not work:

Logging out of iTunes

Deleting partially downloaded .plist file from iTunes Downloads folder

Deleting entire album, then redownloading

It seems strange to me that my anti-web-tracking add-on would prevent only one file out of seven purchased to download (all seven were from the same album, purchased by clicking on "Download Album," not each individual file), but as soon as I disabled my security add-on and logged back into iTunes, the "corrupted" file magically and successfully downloaded.

I don't know if this will solve anyone else's problem, but figured I'd share all the same!

Guess I'll just have to disable my security add-on every time I want to purchase something from iTunes. Gee, that doesn't sem wackadoo at all, Apple. Sigh.

I fought this one long and hard. Tried every trick outlined in the helps. Finally solved it when I turned off our corporate perimeter defense system which is the free version of the Untangle Firewall. After deleting the song one final time and restarting iTunes, the song downloaded on the first try. Clearly this song was somehow triggering our firewall. Many dozens of other songs have passed through with no problem. Beyond that, I cannot explain further. Good Luck! Thanks to "beenit" for putting me on the right track.

I also tried all of the suggestions to no avail. As an experiment this weekend I tried accessing the "corrupt" file from my daughter's network in the Chicago area. Logged in, downloaded, bam. Worked like charm. I have no security software on my home network, but by golly I worked from another network. Weird, but okay!

I just got this one. It sure smells like a new problem. Every other tune in the album downloaded to my iPhone. This got stuck. I tried downloading from iTunes - stuck there.

Nothing new here, no firewall, no antivirus.

Apple support is working with me. In my iTunes account I clicked the "problem" link next to the tune.

I tried downloading to another machine at my home (PPC running Leopard!) -- but it failed. So it's nothing about my machine or my user setup.

I also tried downloading to my phone from AT&T. That also failed.

So I've eliminated network issues, device issues, iTunes version problems, and OS issues.

That leaves server issues. Whatever is causing this problem is either with my user account on Apple's servers (DRM bug?) or, more likely, the servers are malfunctioning.

Apple 2nd tier support reset my password and showed they could download the track.

So I tried again at home. I had to repurchase, but I was given the free download option.

It got stuck again!

I tried a different Arcade Fire track (paid another $1) - that downloaded fine.

My theory is that this is a geography problem. Some tunes are corrupted on some servers. I just happened to hit a bad tune. Every time I download from this area I'll get it.

Next time I'm on the road I'll try downloading from my phone again.

Anyway, 2nd tier support gave up. I guess if I'm bored I'll go to my local genius bar and demonstrate the problem in front of a 'genius' and let him (rare her) play with it.

VICTORY!

I created an SSH tunnel to my web services provider - Dreamhost in CA. Then I used iTunes and the tune downloaded instantly.

That fits the theory that there's a corrupt instance of the tune on the server for my geographic region - Minneapolis-St Paul MN. Now if I could only convince Apple to fix it.
