Keep trying to install update for itunes and keep getting 'invalid signature'

keep trying to install the new updates for itunes and keep getting 'invalid signature' and it won't download

That suggests that the installer is getting damaged during the download.
I'd first try downloading an installer from the Apple website using a different web browser:
http://www.apple.com/itunes/download/
If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

I've had this problem for awhile in Windows XP SP3. Last night, the simplest thing occurred to me...here's what I did (and I'm telling because it worked).
1. Clicked on Start
2. Clicked on Control Panel
3. Chose Add/Remove Programs
4. Found Apple Software Updater and clicked Remove, then responded Yes
5. Went to apple.com and clicked on Support, and then Downloads
6. Downloaded the latest version of Safari ONLY
7. Installed Safari (knowing it would install the latest version of Apple Software Update)
8. AFTER the installation was complete, I clicked again on Start, then All Programs
9. then, clicked on Apple Software Update

Have a look at the articles mentioned here:http://support.apple.com/kb/TS3694

Can anyone help solve this problem?

I've done a search on here and haven't found any solutions posted for it for windows computers. You could try posting in the iTunes For Windows forum and see if you get any suggestions in there (are you able to download other items from the store e.g. a free app ?) - I use a Mac, the only things that I could think of to suggest trying is see if you get the same error on a different iTunes library :
creating and/or opening a different iTunes library : http://support.apple.com/kb/HT1589
or using a different user account on your computer in case it's a problem with that user account.
But you may want to try the iTunes For Windows forum first, apart from anything else you are likely to get better help for the above

It is hardly Apple's fault that Epson can't/won't update their driver, but at least Epson suggest that you use the Gutenprint driver, which in any case is far better that what Epson offer.
You can get it here:
http://gimp-print.sourceforge.net/
You can download the latest version from here:
http://sourceforge.net/projects/gimp-print/
Have you downloaded the recent Apple update to Epson drivers?

first, you just asked me to use MS file Explorer to see what the properties were.,..and to ask what happened. Yes - that's on my hard drive. The problem I have is opening word files in a DB that is web enabled.....I've used Firefox browser for that, and everything else , for years...... When I look at the Tools, and options on FireFox., as your support page noted.....NOTHING is listed in the Applications tab....hence my note asking for help. The file I need to open is a Word file out on a web enabled DB. It's not on my hard drive - I have to problems opening docs there - but for that, I don't use Firefox

Hi
Error -108 memFullErr Ran out of memory [not enough room in heap zone]
Turn off - TimeMachine usually works - re-try.
(the Application down in the Dock - not the Device)
But this can mean many thing's - My first thought is
• Free Space on Start-Up hard disk. How much ? (other disks do not count)

Help with updating to 10.5 from 10.3 and getting "invalid signature" error

I am trying to update to iTunes 10.5 so I can sync my new iPhone 4s but I keep getting the error message "invalid signature". I have tried turning off firewall and antivirus as suggested on this forum to no avail. Also going through Tools, Download only produced the same error. Any Suggestions?

I, too, am unable to update to iTunes 10.5 (iPhone 4) OR Safari. Contunally get "Invalid Signature" messages. I have "changed" each Apple, iTunes and Safari application through Add/Change Programs to no avail. I am forwarned removing iTunes from my PC will cause me to lose all my music. Any suggestions?
