Getting an "unknown publisher" error when downloading itunes

I am trying to download the latest version of Itunes. I keep getting an "Unknown Publisher" message from Internet Explorer. I went through the troubleshooting and removed all apple apps. Now I am stuck. Any ideas?

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?

Why do I get a file security error when downloading itunes.

I try to download itunes, but about halfway through an error messge comes up that says error with file security:get lasterror:5

Hi lizz4321,
A digital ID is made up of three components; a private key, a corresponding public key, and some identifying information. The keys themselves are pretty straight forward, they are just big blobs of numbers used to encrypt and decrypt data. It's the identifying information that gets a bit tricky. On first look, the identifying information looks like plain text. You'll see your name and the issuer's name, a serial number, some dates for when the validity starts and ends. All pretty straight forward.
However, all of this information is actually formatted using something called ASN.1 (it stands for Abstract Syntax Notation) and then encoded using BER (Basic Encoding Rules). When someone creates a digital ID they can put just about anything in there. Per specifications (RFC 5280 if you wanted to look it up) some items are required, and others are optional. Each piece of information that goes into the public-key certificate (the PKC is basically the digital ID without the private key) is contained in an extension. These extensions are identified using an OID (Object ID) and conform to a specification which may either be public or confidential.
There are two possibilities in the case you are seeing. Either, some of the information that Acrobat knows about was formatted or encoded incorrectly, or, there is an optional entry that Acrobat doesn't understand how to decode. My guess is it's the latter possibility. There is a rule that states if an extension is marked as critical, and the application using the public-key certificate (in this case the application would be Acrobat), doesn't understand the extension, then the application is supposed to reject the certificate. It could be the former case (badly formatted data), but without seeing the certificate all I can do is guess.

System services error when downloading itunes

I received an error when updating iTunes. I uninstalled it.
When downloading iTunes from the website, I get as far as System Services and I receive an error.
Retry and Ignore do not work.

Thanks for posting the link. That worked for me just fine. I had previously uninstalled & reinstalled Itunes but that didn't work because I was not removing all the folders associated with it. Have a great week!

I frequently get an "Unknown Import error" when opening an appleworks WP document with Pages.

I am trying to use Pages to convert Appleworks 6.9 WP documents - but I sometimes get an "unknown import error" dialog when I try to import the file into Pages. What does this mean, and is there any way to get around it. (I have not yet converted to Lion, so I can open the document in AW - but cutting and pasting into pages loses a lot of formatting so I would rather not have to go that route.)

Thanks. I don't actually think this is generally the case, though. (In fact, when I have had AW files that included graphics created by AW they seem to have converted smoothly).
Why can't Apple give an informative message instead of "Unknown Import Error"?

Why am i getting an error when downloading itunes...Error 2: apple application support was not found

Tryin to download Itunes on my laptop and the error message pops up. It tells me to to unistall and reinstall and its not fixing the problem??

Let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you? If so, does iTunes launch properly now?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

.msi error when downloading itunes 10.5

.msi error when I try and download itunes 10.5. Anyone have a fix or suggestion?

Which particular msi file does it say can't be found, rock? Several different ones could possibly be mentioned in the context of an iTunes install. (For example, iTunes.msi, Bonjour.msi, AppleSoftwareUpdate.msi ...)

Error when downloading itunes 7 to laptop, somthing about win 32

I have an error that is not letting me download itunes. Can someone help. It says something about valid win 32.

Just a quick point. When you download iTunes do you press run or save?
You need to SAVE the download file, usually in My Download Files although it doesn't really matter. Then once it has been saved you can run it.
But perhaps this is what you did already?

Always receiving error when downloading itunes 8.0.2

I recently purchased an ipod nano and now need to upgrade to itunes 8.0.2 (I'm on 7.6 right now). However, every time I attempt to download, the download fails and I receive the message "error occurred, please try installing again". I have tried about six times now, however I get the exact same message every time. I have a mac mini with OS 10.4.11. According to the requirements page, everything should work. Any ideas?

I am running the same version of OS X and I get the same error message on iTunes 8.02. I also bought and cannot install iWork 08. Sure would like to know what the issue is if you find out.

How do I fix these errors when downloading Itunes?

I keep getting the following errors:
Could not open key: UNKOWN\Components\(some letters and numbers)\(some letters and numbers). Verify that you have sufficent access to that key or contact your support personnel.
This message flashes about three of four times through out the installing.
Once I get past these errors, I eventually get this message, which ultimately ends any attempt to dowload Itunes.
The installer has insufficient privileges to modify this file: C:\Program Files (x86)\Itunes\ITDetector.ocx
I would greatly appricate any help to fix these problems and download Itunes. I just got a new iPhone and I just want to put music on it.

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for performance issues or compatibility with third party software.
The further information area also has notes on your first issue.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

Unknown Publisher error when trying to open forms screen

Hi,
I log in as System Administrator to 11.5.9 Apps. When I try to open any form (eg conc requests), a pop window opens with message "The publisger could not be verified. Install oajinit.exe , Unknown Publisher"
How can I get rid of this?
Thanks,
Dnyanesh

Is it for just you or all users?
If it is only for your user, uninstall Jinitiator with add/remove programs and reinstall it by clicking on a forms link. If it does not install, goto http://hostname.domain:port/OA_HTML/oajinit.exe
If all users see it, your Jinitiator certificate needs to be resigned. You can run adjkey -initialize, and it would also be a good time to upgrade your jinitiator.

Errors when downloading iTunes onto Windows 8

Trying to download iTunes onto new Windows 8 computer (Dell). Once I choose a destination folder and hit "install" it stops within a few seconds saying there was an error (doesn't say what kind of error), and to try again. I have tried 8 million times (...minus a few, maybe). Any suggestions?

Sorry I seemed to have clicked something without knowing,, meant to say that the download does not start at all, is there a reason.
I have an id etc and have moved to a new operating ststem , its a nightmare!
