Received notice to update ITunes. When downloading, got error message "ITunes has an invalid signature" and would not update. Never had an update issue until this download. How do i rectify this error?
Hi, bro2pro.
I would recommend a complete uninstall as outlined in the article below. Make sure to process the uninstall in the order specified.
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
http://support.apple.com/kb/ht1925
Once uninstalled, download iTunes directly from here iTunes 11.0.4 or iTunes.com. Make sure to save the file to your desktop instead of selecting the run option. Locate the file on your desktop, right click and select run as administrator. This should allow the install.
Cheers,
Jason H.

Everytime I try to update to Itunes 11 I get an error message saying that Itunes has an invalid signature and can't be installed? I have tried to install it two times and get the same message each time. Any solutions to my problem?? Those who have installed ITUNES 11 is it hard to work with? maybe im lucky it wont update?? I don't know.
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:

If you use Firefox instead of IE for the download (or vice versa), do you get a working installer? -

My iphone 4 was updated 2 months ago, after updated the safari suddenly stopped working.I open the safari and it stops immediately. i cannot download anything or access any website through Safari. What shall i do to resolve this issue?
Yes but there's no point doing it here. As the Terms of Use make quite clear this is a User to User forum. It's Users like you talking to other Users. It's not a channel to communicate with Apple.

I got a message that my passcode has expired. I never had this happen before. It asks me to enter it instead of using the keypad. Is this a valid request? or is somebody phishing?
If this is an email it is a scam and you should ignore it.

Windows performed an automatic update on my PC this morning. Now, Firefox does not work other than in SAFE mode. I get "Firefox can't establish a connection to the server..." I downloaded and reinstalled the latest version of Firefox and get the same error message. IE works. MS Outlook works. What did Windows do to me this time?
You can find the connection settings in Tools > Options > Advanced : Network : Connection
If you do not need to use a proxy to connect to internet then select "No Proxy" if the default "Use the system proxy settings" setting doesn't work.
See "Firefox connection settings":

The cert8 file gets remade, but the error message still comes. Every new profile gets deleted and the default one always comes back when I keep deleting it in the profile manager.

iTunes has tried to update itself and runs into an error and tells me to manually install. When I d/l and run the iTunesSetup.exe file I always encounter the following error message...
"A network error occured while attempting to read from the file C;|Windows|Installer|iTunes.msi" and iTunes does not update to iTunes 10.4.1.
Anyone know what is creating this error message? Thanks for the help...(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time? -
Bogus error message: "The field jnlp has an invalid value: https."
We are running into a variant of an old bug. With a Windows XP client using JRE 1.5.0_05, we get:
{noformat}Launch File Error: The field <jnlp> has an invalid value: https
Java 1.4+ is required for HTTPS support{noformat}
which of course is a strange thing for a 1.5 JRE to be squawking about. We found a Sun bug report 6433293 that reports this behavior as occuring on Solaris but not on Windows. We're seeing it on Windows. The bug report suggests that the error message text is the "wrong message" and may be totally unrelated to the actual problem (although it is triggered by having an https URL in the "href" attribute of the <jnlp> tag).
Because of our customer environment, upgrading the JRE beyond 1.5.0_05 is NOT an option for us. I googled the message and found one blogpost that suggested the error may be related to the XML encoding (which seems surprising, but they claimed changing the encoding fixed the problem for them). I tried fiddling with the encoding values, but to no avail. Anyone know anything about this bug, and any possible workarounds?We finally found the solution to this, so I will follow up for the sake of posterity. Thanks, Andrew, for the pointer to JaNeLa. While it didn't tip us off to this particular problem, it did get us thinking in the right direction: that there was something about the JNLP file, completely unrelated to what the error message was reporting, that was causing the problem. Turns out that the Java 1.5.0_05 WebStart JNLP parser had a bug, such that it was tripped up by a JNLP file containing more than one XML comment in immediate succession. It seems unbelievable, but it was completely reproducible. Our JNLP file began like this:
<?xml version="1.0" encoding="utf-8"?>
<!-- here's a valid XML comment -->
<!-- here's another valid XML comment, but it freaks out JWS 1.5.0_05 -->
<jnlp spec="1.0+" codebase="https://ourserver/ourApp" href="https://ourserver/ourApp/ourApp.jnlp"/> By accounts, this was patched in 1.5.0_10, and we know that the problem didn't occur in 1.6.0_13. In case anyone else has this problem, that's something to look for. (Note: this isn't the only cause of this erroneous error message. It apparently got printed out when the parser was unhappy about various things. I saw another report that someone had a problem with their "encoding" attribute value on their xml header, and fixing that solved their problem.) -
HP smart web printing is incompatible with firefox 4.0. What can be done to resolve this issue?
having recently upgraded to Mozilla's Firefox 4.0 it has disabled the 4.6 HP smart web printing saying it is incompatible with Firefox 4.0? Is there any way around this inconvenience of not having the ability to use this terrific HP pdct as do not have ability to print from a website using their print feature nor simply selecting print on the Firefox browser?
thank youAnytime that there is a browser upgrade, it affects add ons functionality. If it is in the works to make it compatible, then it simply takes time for our team to create the necessary changes. But, as history has shown, the changes are never as easy as you would think, and occasionally is not compatible without a complete rewrite of the program. If it is made compatible, it will be listed when available on the Web Printing homepage.
