Found this and it solved my version of the problem.

I was having this problem. I seem to have been able to solve it by switching my language from English to British English in the System Preferences. This is what my language settings should have been anyway and I'm not entirely sure why they were not set like this.

Un-freakin'-believable Apple. Really? Really!? I had the same error. I am downloading the full iTunes release now. This better work Apple. You guys (Apple) are getting sloppy!!!

Confirmed: downloading the full iTunes 10.6.1 and installing that fixed the issue and iTunes is working again. Wow Apple. Someone in QA needs a slappin'!!

I twon't allow me to download from the apple support site. Seems that the site is down? any suggestions?

Tried downloading it again, good thing that it is now in my downloads folder. i don't know if the site just really takes a while to load. i don't have problems browsing other sites. I always experience this with apple site.

Totally agree with Dan here. First the 10.6 patch gorks my iTues and then this? Sloppy and nasty, and I've been an Apple customer since 1987. Too bad Steve passed, QA has died. Had to download and install the full app from the product site and was embarrased to have to do so.

I already installed 10.6.1 using software update before I started having this problem. Do I have to roll back to the previous version I had before that install and THEN download the 10.6.1 from the Apple support site?

I just downloaded the iTunes and then installed it over the existing 10.6.1 and it worked fine.

Not again, Apple! Come on. The last version of itunes crashed all time when playing back videos and I had to re-install an earlier version of itunes. Painful and embarrising.

I was hesitant to install 10.6.1 because of this and now this issue about "this version of itunes is not correctly localized..."

Is Apple software turning into Microsoft software? Apple get you s-t together. You cannot release versions with bugs like this. Respect your customer and the establised Apple culture.

Changing the language from "U.S." to "British" did not work for me, and why should I have to do that in the first place?!

As most people in this thread what worked for me was to download the full version of itunes.

You can get it from Apple website: http://www.apple.com/itunes/download/

Needless to say I am disapointed and furious that I had to spend time and energy on this. I will not update itunes for a long time.

I had this issue with a newer version of iTunes. But I went to Apple's site & redownloaded & installed iTunes. Opens & works fine now.
