Can't Download An Update!

Apple iPhone - I Can't Download An Update!

I get this every time I try to download an iTunes+Quicktime update. The error message reads like this:

"iTunes+Quicktime' has an invalid signature. The download has been removed.

This is the message I get from Apple Update. It's what pops up on the screen after waiting a long time for the download.

I've tried many times. I've tried both download only and download +install...it doesn't matter...I still get this message.

Can anyone shed some light on why this is happening?

First I assume that you are either having this issue on a PC or in BootCamp.

I recently booted my Mac into Windows XP and was surprised to be offered this Apple Software Update for iTunes. I had already installed QT, but not iTunes.

I installed iTunes + QuickTime without any problems. I don't remember any signature issues. Did you install the updated BootCamp? I got BC v2.2 for XP, but if you are running Vista or & then you may need BC v 3.1. That maybe where the issue is.

If not, then you can go to Apple > Support (tab) and then look for downloads. Read the requirements before you start any install, though. That may point you to any issues or prerequisite updates you need.

Your user name made me think you were using a Mac, but the iTunes + QT says PC or BootCamp. That combo is not offered for a Mac, and that gave it away.

It is really easier to suggest answers if you lay it out, rather than leave little bread crumbs of clues as to you hardware & software. See my signature below.

Oh! BTW! Your iPod, and I assume your iPhone or iPad can only be synced to either Macs or Windows-boxes, not both. I just happened to try changing an old iPod over to syncing in Windows and otherwise again would not have recognized the Tunes + QT offering.

Delete the whole install and start over

I found this and it made things right again with my Vista PC. Apparently my software update was messed up and needed repair. This blurb from Apple Support seems to explain it and say how to fix it. So if any of you have this problem...this is the fix. Thanks to all who replied to help in this matter. I appreciate it very much.
Here is the Apple web page.

And yes I did reinstall iTunes-Quicktime. The cool thing was that it remembered all my library stuff and structures etc. That made me happy 'cause I was worried about that. :-)

3. In Windows XP and Windows 2000, click the Change button.

4. Click Repair.

5. In Windows XP and Windows 2000, once it is repaired, click Finish.
