BleepingComputer.com: Itunes Cannot Play..

Yesterday, I ws downloading an update for itunes. It tunred out fine, and so later on, I shut down my computer normally.

Now, when I came back to it today, for some odd reason, when I try to play an mp3 file with Itunes,
I get an error message saying Itunes cannot run because some of its required files are missing, and then it says to re-install it.

I have re-installed it about 5 times, and then I've done a system restore before I got the update, but Itunes still won't start up.

Anyone know the problem?

Does it tell you what the file name is?

The file name? If you mean the itunes applicaiton itself, then no..

Basically, instead of itunes coming up, all I see is an error message.

No, I mean't the file in which itunes is missing.

No...

Well, I found out a way to repair this. Apparently it has been widepsread in vista users...thanks for trying to help though. =)
