Error 100008 - Corrupt file message when downloading iTunes

cosmini,

It is documented in the Apple Knowledgebase which can be searched at http://www.apple.com/support/

This article lists the site:
http://docs.info.apple.com/article.html?artnum=93434

As for ports, the store uses http and https which is port 80 and 443.

These articles discusses which applications need to be allowed to access the internet, such as when using Windows firewall:

Hope this helps,

I had the same problem, here's what I had to do to fix it.

I recently switched to CA Security for anti-virus and firewall protection (provide by Time Warner). I went in and turned off CA's firewall protection (I turned Window's Firewall ON)and I was FINALLY ABLE TO DOWNLOAD MY MUSIC. To turn CA's firewall off:

1) Open CA Security Center (on the Task Bar or through the start button)
2) Click the "double-down" arrow on the far right of "CA Personal Firewall"
3) Click "Open Advanced Settings" under "CA Personal Firewall"
4) Click "Disable CA Personal Firewall"
5) Resume your downloads through iTunes
6) Re-enable your firewall

Hope this helps everyone who's encountered the same problem!

EcoTEC07,
Same problem with iTunes. Took the rick to shutdown firewall completely to download, but that didn't work for me. I activated Windows Firewall and then I was able to dload. Thanks for your help.
The most frustrating part of my whole experience was the lack of response from any of the application parties involved. It's just BUY/USE my product, but don't expect any help from us!!

Just switched to Time Warner CA security software and am having the same problem. Turned off firewall as stated below and it worked. Not to be negative, but nothing but headaches since Time Warner took over. Shouldn't have to turn off your firewall completely to download from iTunes.

this is really elementary, for Apple to fix. They have to just tell us what ports their software is using, so we can open these ports, or what site exactly it's hitting so we can configure the firewall. I hope Apple is listening here, this is a basic request!!!

Contact the iTunes Store customer support department through the form at the bottom of their web page and explain the problem to them.

Thank you! Omg it fixed the same thing you had problems with on mine....thank you again

a big thanks to you for helping me too.
is there a firewall i can leave on that wont buggar the downloads? pete

You are AWESOME! Itunes support has been completely useless for a couple of months now and recommended really bad solutions that didn't work. I gave up on them. Thank you very much.
